Human body cells contain 46 chromosomes- The first 22 pairs are called.pdfkrishnac481
Human body cells contain 46 chromosomes. The first 22 pairs are called autosomes, and they
contain numerous genes that affect the traits of the individual. The last pair, number 23, are the
sex chromosomes. The sex chromosomes determine gender (i.e., either male or female), but there
are other genes on this pair of chromosomes as well. Males sex chromosomes are XY, while
female sex chromosomes are XX . The gametes in a human (either egg cells or sperm cells)
contain only 23 chromosomes. Fertilization, the fusion of an egg and a sperm, restores the total
of 46 chromosomes in a human zygote. Non-gamete cells are called somatic cells, and they have
all 46 chromosomes in them. 1. Your sex chromosomes: XX Just as in Mendel's pea plant
experiments, genes in humans can be dominant or recessive, and the results of "crosses" can be
predicted using Punnett squares. A phenotype is the physical expression of a gene (made up of a
pair of alleles). The genotype is the actual genetic makeup of the allele pair. An individual
having two identical alleles for a gene is said to be homozygous. There can be homozygous
dominant or homozygous recessive combinations. Dominant traits are represented by capital
letters; recessive by lower case letters. An individual having non-identical alleles for a gene is
said to be heterozygous. Note that the phenotype of a heterozygous individual is determined by
the dominant gene. Dominant alleles tend to cover up the presence of any recessive alleles. In a
case of alleles that show simple dominance / recessiveness, it is not possible to know if an
individual who possesses a dominant trait has the homozygous dominant or the hatarnzunniic

Biology 103 Laboratory Exercise – Genetic Problems
Introduction
Although the science of genetics has become a highly sophisticated discipline dealing
with the interactions of hereditary factors at the molecular level, it has its roots in the
basic laws of heredity initially discovered and presented by Gregor Mendel more than
one hundred years ago. Mendel's success in discovering these laws was due largely to his
application of the simple rules of mathematical probability - the laws of chance - to his
observations concerning the inheritance of certain characteristics in the garden pea plant.
Reginald Punnett and the Punnett Square
The Punnett square is a diagram used by biologists to determine genotypic probability
within the offspring from a particular genetic cross. The Punnett square shows every
possible genotypic combination of maternal alleles with the paternal alleles for a genetic
cross. Punnett squares only give probabilities for genotypes, not phenotypes. The square
diagram was designed by the British geneticist, Reginald Punnett (1865-1967) and first
presented to the science community in 1905. Punnett’s Mendelism (1905) is considered
the first popular science book to introduce genetics to the public.

The first step in solving a genetic problem is to establish the genetic symbols you will use
in your problem solution. Stay consistent by using these same symbols throughout the
problem solving process.
Represent dominant and recessive alleles (different forms of a gene) using traditional
genetic symbols. Dominant alleles should be represented with the capital version of an
alphabetic letter while using the lower case version to show recessiveness. For example:
B = black color, b = white color.
Each individual gene or trait is diploid (2n) in nature and therefore, must be represented
with two alleles. Continuing with the alleles mentioned previously, an individual may
have the genetic makeup BB, Bb, or bb when using those alleles.
Remember that gametes (sperm and egg) are haploid (n) and can only provide one allele
per trait. For example: B or b
An individual’s genotype contains the possible gametes that can be expected to be
produced by that individual. Much of genetics revolves around the probability of the
makeup of gametes. If the individual is homozygous, all of the gametes produced will
possess the same kind of allele. For example, an individual with the genotype BB would
be expected to produce only B gametes and individuals with genotype bb would produce
only b gametes.
If the individual is heterozygous, that is the individual’s genotype contains one dominant
allele and one recessive allele (Bb), the gametes produced will possess one or the other of
the two forms of the gene – B or b. ...

KDEL sequences target ER lumen proteins to the Golgi KDEL receptors bind proteins with the KDEL sequence in the ER lumen KDEL receptors release proteins with ER retention sequences in the Golgi lumen binding of a protein with a KDEL sequence to a KDEL receptor causes a conformational change in the KDEL receptor that allows its packaging into retrieval vesicle. When the KDEL receptor releases its cargo in the ER lumen, the protein returns to its unbound conformation.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A- Mendelian Genetics Questions 1- In pea plants a purple flower (P) i.docx
1. A. Mendelian Genetics Questions 1. In pea plants a purple flower ( P ) is dominant and a white
flower ( p ) is recessive. a. What is the genotype of a pure hreeding white plant? b. If a pure
brecding purple plant is crossed with at pure breeding white plant, what phenotype is expected
for the offspring? 2. In pea plants a tall plant (T) is deminant and a short plant ( t ) is recessive. a.
Use a Punnett square to show the cross between two heterory gous tall plants. Parent genotypes:
b. What would be the predicted genotype and phenotype ratios of the offipping? Cieastype Matid
Fhrefype Matie 3. In hamsters, black hair ( B ) is dominant to brosin hair (b) and shott hair (H) is
dominant to long hair (h). A black, long-haired hamster (Bbhh) is erossed with a brown, short-
haired hamster (bbHh). a. What pereentage of the offspring will be brown with long hair? Use a
Punnett square to show the genotype and phenotype ratios of the offspring. 4. In rabbits, white
coaf color ( C a ) and black coat color ( C A ) are codominant, and both of these alleles are
dominant over albino (c). Helerovygotes ( C C ) are spored. c. Use a Punnet square to show the
genocype and phenotype ratios of the oflspring from a heterorygous black-coated rabbit and a
bornorygous white-coated rabbit. Wivary or Rot Panoyer Rosit 5. In plants known as "four
d'elocks", the allele for red fower color is incompletely deminast over the allele for white flower
coloe. Heterorygous pink flewered four "elocks were allowed to self-pollinate. c. Use a Punnett
square to show the genotype and phcnotype ratios of the offlspring. d. In theory, what pereeti of
the offipping would be penk? Perecntage pink? 6. Skin color in humans is determined by a
(ctadient fult itr the blanti). inberitance system, possibly involving as many as 9 genes. For
simplicity let ins consider the inflwence of 2 genes: A and B , where the dominant allele (upper
case A or B) darkens skin colot. Suppose a woman who is AABb reprodnces with a man who is
Aabb: b. List all of the possible genetypes of the pametes that could be produced by each parent.
c. Use a Punnet square to show the genathpe ratio of the oflispring.
