Human heredity is determined by chromosomes, which are structures in the nucleus that contain genetic information passed down between generations. A karyotype maps out a person's entire set of chromosomes and can be used to identify genetic disorders. Traits are transmitted through dominant and recessive alleles, codominant alleles, sex-linked inheritance, and X chromosome inactivation. Common genetic disorders include sickle cell disease, cystic fibrosis, and Huntington's disease, which result from changes in single genes. Some genetic mutations can provide advantages, like resistance to malaria. The human genome project worked to sequence and identify all human genes to further understand genetic inheritance and open up possibilities for new treatments.

1. The human genome project mapped the entire human genome and found it contains around 31,000 genes, fewer than organisms like fruit flies and roundworms.
2. Human traits are determined by single genes, but most are influenced by multiple genes and the environment. Scientists use tools like pedigrees and karyotypes to study inheritance of traits.
3. Examples of genetic disorders caused by single gene mutations include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, and phenylketonuria (PKU).
Hereditas
1) Heredity is the passing of traits from parents to offspring. Traits like eye color, hair color, and body shape are inherited through genes.
2) Genes are located on chromosomes and determine physical characteristics. Chromosomes contain DNA and are passed from parents to children during reproduction.
3) DNA is made of nucleotides with a phosphate group, sugar, and nitrogenous base. The order of these nucleotides make up the genetic code and determine traits. DNA self-replicates by using each strand as a template to make a new double helix.

This document discusses the contributions of Gregor Mendel to genetics. It notes that he was the first to use the term "genetics" and coined the term. He discovered the basic principles of heredity by breeding and studying thousands of pea plant varieties. His work helped lay the foundations for modern genetics and cloning techniques.
Lecture on history of genetics
Genetics is the scientific study of genes, heredity, and genetic variation in living organisms. Modern genetics began with Gregor Mendel's experiments in the mid-19th century which showed that traits are passed from parents to offspring via discrete units of inheritance called genes. In the early 20th century, scientists discovered that genes are located on chromosomes and arranged linearly. Later experiments in the 1920s-1950s identified DNA as the molecular basis of genes and the structure of DNA was determined to be a double helix, showing how genetic information is stored and passed to new cells.
Basic genetics
This document provides information on genetic concepts including genes, DNA, chromosomes, genotypes and phenotypes. It defines key terms and describes patterns of inheritance such as dominant, recessive, X-linked, autosomal and codominant traits. Examples are given of human genetic disorders and their inheritance patterns. Questions at the end test understanding of calculating inheritance probabilities and determining modes of inheritance from pedigree charts.

This document discusses gene expression patterns in tailed and tailless ascidian species. It finds that:
1) Tailed and tailless species contain most known notochord genes, though tailless species do not form a notochord structure.
2) Digital normalization performs comparably to or slightly better than raw read assembly in transcriptome sequencing.
3) Metamorphosis genes are expressed much earlier in tailless Molgula species than in other ascidians, representing a potential pre-adaptation to losing the tail.

Genetic disorders
Gregor Mendel's work in the 1860s laid the foundation for understanding inheritance of traits. Later, Francis Crick, James Watson, and Rosalind Franklin discovered the structure of DNA. This led to understanding how genetic information is passed from parents to offspring. Many genetic disorders result from mutations in DNA, including Down syndrome from an extra chromosome 21, Klinefelter syndrome from an extra X chromosome, and Turner syndrome from a missing X chromosome. Other genetic disorders discussed include sickle cell anemia, cystic fibrosis, Tay-Sachs disease, muscular dystrophy, hemophilia, Huntington's disease, phenylketonuria (PKU), and ALS. Both dominant and recessive inheritance patterns were
Chapter 2The Genetic and Evolutionary Roots of Behavior
1) The passage discusses genetics, evolution, and behavior from a biological perspective. It explains how genes govern cellular functions and are passed down through generations, resulting in inherited traits and behaviors.
2) Darwin's theory of evolution by natural selection is described, where genetic variations that provide reproductive advantages are more likely to be passed on, shaping organisms over generations. Behaviors as well as physical traits have evolved in this manner.
3) Evidence for evolution includes the fossil record, molecular analysis of genomes across species showing common ancestry, and examples of observed natural selection in modern organisms. Intelligence has components of both genetic inheritance and environmental influences.
Pertemuan 1. history of genetics

Stem cell project
The document discusses several topics related to genetics including heredity, genetic disorders, stem cell research, and arguments for and against stem cell research. It explains that traits are controlled by dominant, recessive, or co-dominant alleles and are inherited from parents. The Human Genome Project sought to map all human genes. Genetic disorders can be single gene, chromosomal, or multifactorial. Stem cell research offers potential cures but also raises ethical issues. Both proponents and opponents of stem cell research are discussed.
GENETICS
This document defines several key genetic terms and concepts:
- Genes are the basic units of heredity located on chromosomes that determine traits. A genome is the full set of genetic material in an organism.
- Genotypes are an individual's genetic makeup at a locus, while phenotypes are the observable traits that result from gene expression.
- Dominant alleles will be expressed even if paired with a recessive allele, while recessive alleles require two copies to be expressed.
- Inheritance patterns like autosomal recessive, autosomal dominant, X-linked, and mitochondrial are described through examples like cystic fibrosis and hemophilia.

2) Human Genetic Disorders - Genetic disorders have a molecular basis when changes in DNA alter proteins and phenotypes. Examples include sickle cell disease, cystic fibrosis, and Huntington's disease. Chromosomal disorders like Down syndrome can occur from nondisjunction.
3) Studying the Human Genome - The final lesson likely discusses the Human Genome Project which sought to sequence the entire human genome to better understand human genetics.
James Watson and Francis Crick - famous scientists
James Watson and Francis Crick discovered the structure of DNA in 1953. They found that DNA has the structure of a double helix, with two strands coiled around each other. Each strand is a sequence of four chemical bases - adenine, guanine, cytosine, and thymine. The order of these bases provides the genetic code that makes each organism unique. This discovery was groundbreaking in explaining how genetic information is stored and passed down. It revolutionized the fields of biology, genetics, and medicine. Watson and Crick, along with Maurice Wilkins, were awarded the Nobel Prize in 1962 for their work unraveling the structure and function of DNA.

It also summarizes the human genome project which started in 1990 to identify all human genes, discusses its ethical, legal and social implications, and how it changed laws like GINA. The project also compares genetic disorders like single gene, chromosome abnormalities and multifactorial disorders. It discusses how genetic counseling can help parents with genetic disorders and how karyotypes are used to predict genetic disorders. Rory's presentation includes four arguments against cloning endangered or extinct species and a conclusion that cloning such species is risky and resources would be better spent on other research.
Genetics research project
This document discusses several key genetics concepts including dominant and recessive alleles, Punnett squares, pedigree charts, single gene disorders, chromosome disorders, and multifactoral disorders. It also covers topics like the Human Genome Project, genetic counseling, cloning, biotechnology foods, and how biotech foods could help address issues like world hunger and malnutrition.
BiologyEcology-222-Genetics-topic1a.pptx
This document provides a history of genetics, describing major events from ancient times through the 20th century. It outlines old ideas that had to be overcome, like spontaneous generation and inheritance of acquired traits. Key discoveries include Mendel's work in 1866, rediscovery in 1900, Morgan's work linking genes to chromosomes in 1910, and Watson and Crick's DNA structure determination in 1953. The current understanding is that DNA sequences encode instructions to build organisms, with genes expressing as RNA and protein. Mutations occur randomly and natural selection favors those that increase fitness.
Human cloning
This document discusses human cloning and genetic engineering. It provides background on genetics and the human genome project. It then discusses genetic disorders and scientific advances in cloning, including Dolly the sheep. Both arguments for and against human cloning are presented. While cloning could help infertile couples or allow people to be cloned, it may also lead to overpopulation or premature aging. The conclusion is that the benefits of human cloning outweigh the risks.
Genetic Disorders ppt.pptx
This document discusses genetic disorders and provides information on the following topics:
1. It defines genetic disorders and differentiates between genetic and congenital disorders.
2. It discusses various genetic concepts including trisomy, monosomy, polysomy, and aneuploidy.
3. It describes several specific genetic disorders including Down syndrome, Turner syndrome, and Klinefelter syndrome providing details on their causes and clinical manifestations.

Owl pellet dissection
An owl pellet dissection found bones from 2 animals, including 2 humeri, 1 femur, 2 lower jaws, 2 skulls, 3 vertebrae, 2 shoulder blades, 2 ulnas/radii, 2 ribs, 6 pelvic bones, and 2 tibias/fibias. The pellet contents indicate the owl's diet consisted of at least 2 animals, and as a tertiary consumer, the owl preys on rats that eat plants.
Earthworm dissection lab
The earthworm belongs to the phylum Annelida. It has many segments and searches for food at night in the soil. Earthworms are important for enriching soil by turning over tons of soil and bringing nutrients to the surface. The lab involved dissecting an earthworm to observe its external and internal anatomy, including organs like the brain, hearts, and digestive system. Key differences from humans are that earthworms have multiple hearts and need to keep their skin moist at all times.
Ecology notes
Ecology notes discuss key concepts in ecology including:
- The biosphere, which encompasses all life on Earth from 10,000 meters below to above the surface.
- Ecology, which studies interactions between life forms and between life and non-living elements.
- Levels of organization from atoms to biomes.
- Biotic factors like producers, consumers and abiotic factors like the sun and energy.
- Food chains which flow in one direction and complex food webs with interactions between multiple organisms.
Week12warm ups
We have studied cell biology, genetics, and evolution in this class so far. The remaining topics to cover are physiology and ecology. Physiology will look at how living organisms function, while ecology examines the interactions between organisms and their environments.
Week 15 warm up
The human body has organ systems that work together to maintain homeostasis, keeping the human body stable despite changes in the outside environment. Homeostasis refers to the body's ability to remain relatively stable through the coordinated actions of organ systems. This document discusses physiology unit objectives related to how the human body achieves homeostasis.
Natural selection lab
This document describes an experiment to test how different beak shapes affect a bird's ability to gather food. Students will act as birds with spoons, forks or sporks to collect beans and peas, and the amounts gathered will be counted. The hypothesis is that the spork bird will collect the most food and the fork bird the least. Students will rotate roles as the bird, nest and counter. They will then analyze the results and factors affecting food collection.
Week 9 warm ups
The document outlines five areas of evidence for evolution: biogeography, fossils, anatomy and embryology, genetics and molecular biology, and testing natural selection. For each area, it lists questions about how the evidence in that area relates to evolutionary history, processes, and theory.
Week 9 warm ups
The document outlines evidence of evolution from biogeography, fossils, anatomy, embryology, genetics and molecular biology, and studies of natural selection. It discusses how the geographic distribution of species relates to their evolutionary history, the use of fossils to trace descent of modern species, homologous structures and similarities in embryonic development suggesting evolutionary change, molecular biology's ability to trace evolution, and how research on Galapagos finches shows natural selection in action.
Week 10 warm up
Next week there is an exam on Chapter 16. Students should prepare by studying assignments like the Darwin video, chapter 16 worksheet, warm ups, and natural selection lab. They should also look over the chapter at home and study in a group for at least 30 minutes each day. Individuals do not evolve, groups evolve.

Periodfourpresentation.
This document summarizes evidence that supports the theory of evolution from four perspectives: biogeography, the age of the Earth and fossils, comparative anatomy and embryology, and genetics and molecular biology. Each section provides examples for how scientific observations in these areas help trace evolutionary relationships and document how species have changed over time from common ancestors through natural processes like natural selection. The document also discusses how recent research on Galapagos finches supported Darwin's original hypotheses about natural selection by showing adaptations to seasonal changes.
Week 8 warm ups
Charles Darwin was a scientist who introduced the theory of natural selection, proposing that organisms evolve over generations through a process where favorable traits become more common in a population due to increasing an organism's ability to survive and reproduce. He made great contributions to the study of evolution by first introducing the idea of natural selection. However, the document incorrectly states that Darwin proposed humans evolved from monkeys, when he actually proposed humans share a common ancestor with modern apes.
Chapter13 worksheets
This document provides information about RNA, transcription, translation, and gene regulation. It begins by contrasting the structures of RNA and DNA, explaining the three main types of RNA, and describing the process of transcription. It then discusses the genetic code, how translation works using tRNAs and ribosomes to assemble amino acids into proteins, and the central dogma of molecular biology. The document concludes by covering gene regulation in prokaryotes and eukaryotes, including how operons control gene expression and how transcription factors regulate development.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Epistemic Interaction - tuning interfaces to provide information for AI support
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
