Gregor Mendel conducted experiments with pea plants in the mid-1800s that formed the basis of genetic inheritance. By breeding pea plants with different traits like plant height, seed color, and pod shape over multiple generations, Mendel discovered that traits are passed down through discrete factors, now called genes. His experiments led to two laws: 1) the Law of Segregation states that organisms pass one of two alleles to offspring and traits segregate independently, and 2) the Law of Independent Assortment states that different gene pairs assort independently during reproduction. Mendel's work established the foundations of genetics.

Trude Schwarzacher: #ECA2015 European Cytogenetics Conference plenary talk:15...Pat (JS) Heslop-Harrison
Trude Schwarzacher Plenary talk at European Cytogenetics Conference, Strasbourg, July 2015, to commemorate 150 years since publication of Gregor Mendel's work on the laws of genetic inheritance in 1865. This was two decades before chromosomes were described.
2015 marks the 150th anniversary of the presentation and publication of Mendel’s seminal paper presenting his Laws of Heredity. One expects that the unexciting and uninformative title Versuche über Pflanzenhybriden (Studies of plant hybrids) in his paper was one reason it was ignored – the importance of a paper title for finding work is something we have discussed here on AoBBlog and regularly among Annals of Botany Editors! In the Slideshare talk, Trude Schwarzacher discussed research in Mendel’s time, when ‘blended inheritance’ was accepted, and then how Mendel came to carry out the work. Not least, he was taught by the physicist Christian Doppler at the University of Vienna, no doubt implanting the centrality of numeracy and what we now consider statistics, to understanding all phenomena, including those of biology.
Trude also points out that of the seven characters Mendel worked with in pea, two are still very relevant to breeding of modern crops: the terminal flowering character, and dwarfism of the whole plant. The synthesis of the results in Mendel’s original paper, even today, is remarkable with considerable interpretation and presentation of a general model of inheritance: I do wonder how many modern referees would quibble about "unsubstantiated extensions"? Trude discusses Mendel’s interactions with another important botanist of the time, Karl Wilhelm Naegeli of Munich; in some ways, though, this was unfortunate in that firstly, it is not clear how much Naegeli understood the significance of Mendel’s genetical results and the laws of heredity, and also had the suggestion to work with the hawkweeds, genus Hieraceum, which includes many polyploids and apomicts. Hardly a model species to use to understand the principles of genetic inheritance, and no doubt disheartening for the Monk by then working in Brno! The final section of Trude’s talk puts Mendel’s work into the context of chromosomes, as might be expected in a cytogenetics conference, although cell division and chromosomes were not described until later in the 19th century – the slideshare embedded above shows some images from these early work, with more recent results from her own lab.

post 1
Gregor Mendel is an Augustan monk. He lived and worked in a abbey in Brunn, Astria. In the 1860's he begin his study of genetics and heredity by breeding garden peas.
The first principle I will like to discuss is the law of segregation. During gamete formation, the alleles for each gene segregate (separate) from each other so that each gene carries only one allele for each gene. The example..
Round seeds segregation R
R
Wrinkled Seeds r
r (gametes)
The other I will discuss is the law of dominance. Its stated as, "In a cross of parents that are pure for contrasting traits, only one trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype. You have a tall plant having the gene TT and a short plant having the gene tt.
Tall pea plant
T T
Short Pea plant t Tt Tt
t Tt Tt
This Punnet square shoes that if we cross a tall pea plant with genotype TT and a short pea plant with genotype tt. All offsprings will be tall with the genotype Tt. During gamete production, each egg and sperm cell receives just one of the two gene copies present in the organism, and the copy allocated to each gamete is random (law of segregation). In the law of dominance, an offspring receives a pair of alleles for a trait by inheriting homologous chromosomes from the parent organisms; one allele for each trait from each parent. Each parent contributes a single gamete, and a single randomly successful allele copy to their offspring and fertilization. Gregor Mendel, through his work on pea plants discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
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.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Mendel.html
1. Gregor Mendel
The basic laws of
heredity were first
formed during the mid1800’s by an Austrian
botanist monk named
Gregor Mendel.
Because his work laid the
foundation to the study of
heredity, Mendel is
referred to as “The Father
of Genetics.”
2. Mendel’ Pea Plants
Mendel based his laws on his studies of
garden pea plants. Mendel was able to
observe differences in multiple traits
over many generations because pea
plants reproduce rapidly, and have many
visible traits such as:
Seed Color
Plant Height
Green Yellow
Tall
Short
Pod color
Green
Yellow
Seed Shape
Pod Shape
Wrinkled Round
Smooth Pinched
3. Mendel’s Experiments
Mendel noticed that some plants always produced offspring
that had a form of a trait exactly like the parent plant. He
called these plants “purebred” plants. For instance, purebred
short plants always produced short offspring and purebred tall
plants always produced tall offspring.
X
Purebred Short Parents
Short Offspring
X
Purebred Tall Parents
Tall Offspring
4. Mendel’s First Experiment
Mendel crossed purebred plants with opposite forms of a trait.
He called these plants the parental generation , or P generation.
For instance, purebred tall plants were crossed with purebred
short plants.
X
Parent Tall
P generation
Parent Short
P generation
Offspring Tall
F1 generation
Mendel observed that all of the offspring grew to be tall
plants. None resembled the short short parent. He called this
generation of offspring the first filial , or F1 generation, (The
word filial means “son” in Latin.)
5. Mendel’s Second Experiment
Mendel then crossed two of the offspring tall plants produced
from his first experiment.
Parent Plants
Offspring
X
Tall
F1 generation
3⁄4 Tall & 1⁄4 Short
F2 generation
Mendel called this second generation of plants the second
filial, F2, generation. To his surprise, Mendel observed that
this generation had a mix of tall and short plants. This
occurred even though none of the F1 parents were short.
6. Mendel’s Law of Segregation
Mendel’s first law, the Law of Segregation, has three parts.
From his experiments, Mendel concluded that:
1. Plant traits are handed down through “hereditary
factors” in the sperm and egg.
2. Because offspring obtain hereditary factors from both
parents, each plant must contain two factors for every trait.
3. The factors in a pair segregate (separate) during the
formation of sex cells, and each sperm or egg receives
only one member of the pair.
7. Dominant and Recessive Genes
Mendel went on to reason that one factor (gene) in a pair
may mask, or hide, the other factor. For instance, in his
first experiment, when he crossed a purebred tall plant with
a purebred short plant, all offspring were tall. Although the
F1 offspring all had both tall and short factors, they only
displayed the tall factor. He concluded that the tallness
factor masked the shortness factor.
Today, scientists refer to the “factors” that control traits as
genes. The different forms of a gene are called alleles.
Alleles that mask or hide other alleles, such as the “tall”
allele, are said to be dominant.
A recessive allele, such as the short allele, is masked, or
covered up, whenever the dominant allele is present.
8. Homozygous Genes
What Mendel refered to as a “purebred” plant we now know
this to mean that the plant has two identical genes for a
particular trait. For instance, a purebred tall plant has two tall
genes and a purebred short plant has two short genes. The
modern scientific term for “purebred” is homozygous.
short-short
short-short
short-short
X
Short Parents
Short Offspring
According to Mendel’s Law of Segregation, each parent donates
one height gene to the offspring. Since each parent had only
short genes to donate, all offspring will also have two short
genes (homozygous) and will therefore be short.
9. Hybrid Alleles
In Mendel’s first experiment, F1 offspring plants received one
tall gene and one short gene from the parent plants. Therefore,
all offspring contained both alleles, a short allele and a tall
allele. When both alleles for a trait are present, the plant is said
to be a hybrid for that trait. Today, we call hybrid alleles
heterozygous.
tall-tall
short-tall
short-tall
short-short
X
Parent Short
P generation
Parent Tall
P generation
Offspring Tall
F1 generation
Although the offspring have both a tall and a short allele, only
the tall allele is expressed and is therefore dominant over short.
10. Dominant Alleles
Mendel observed a variety of dominant alleles in pea plants
other than the tall allele. For instance, hybrid plants for seed
color always have yellow seeds.
Green & Yellow Allele
Yellow Seed
However, a plant that is a hybrid for pod color always
displays the green allele.
Green & Yellow Allele
Green Pod
In addition, round seeds are dominant over wrinkled seeds,
and smooth pods are dominant over wrinkled pods.
11. Law of Independent Assortment
Mendel’s second law, the Law of Independent Assortment,
states that each pair of genes separate independently of each
other in the production of sex cells. For instance, consider
an example of the following gene pairs:
According to Mendels’ Law of Independent
Assortment, the gene pairs will separate during
the formation of egg or sperm cells. The plant
will donate one allele from each pair. The plant
will donate either a yellow or green seed allele,
either a yellow or green pod allele, and a
wrinkled or round seed allele. It will always
donate a wrinkled pod shape. The donation of
one allele from each pair is independent of any
other pair. For example, if the plant donates the
yellow seed allele it does not mean that it will
also donate the yellow pod allele.
