4a) The frequencies of alleles A and B in a pool of gametes are A= B= 0.5. The gametes randomly unite to form 200 zygotes. What are the numbers of each genotype among the zygotes? (5 pts)

b) As these zygotes develop into adults, 92% of individuals with genotype AA, and 80% of individuals with genotype BB were captured and killed by a predator because they were too slow. Does the surviving population of adults appear to be in HW equilibrium? (17pts)

c) Now assume that the surviving adults mate randomly to form 200 zygotes. Does this next generation of zygotes appear to be in HW equilibrium? (5pts)

d) What is the moral of the story? (5pts)

In an isolated population, the frequencies of the IA, IB, and i alleles of the A–B–O blood type gene are, respectively, 0.15, 0.25, and 0.60. If the genotypes of the A–B–O blood type gene are in Hardy–Weinberg proportions, what fraction of the people who have type A blood in this population is expected to be homozygous for the IA allele?

1. you are evaluating autosomal recessive condition A (alleles A and a) and B (alleles B and b) which you hypothesize are on different chromosomes. You are given 7 wildtype (homozygous dominant) female flies and 7 male flies that are homozygous recessive. What genotypic ratio would you expect in the F1 generation produced? 2. you mate the F1 females with males that are homozygous recessive for both disease A and B to produce an F2 generation. What phenotypic ratio would...

Locus A has two alleles (A and a) while locus B has two alleles (B and b). The recombination frequency between locus A and locus B is 11%. A F1 heterozygote in trans configuration is mated with an aabb individual. What are the expected phenotypic percentages in the resulting progeny? Report your percentages to the tenths place and in the following format, replacing the "0.0" with your percentages.

An autosomal gene is segregating two alleles, R and r, with respective frequencies 0.3 and 0.7. If mating is random, what are the expected frequencies of the genotypes? Now suppose that every individual in the population mates with a sibling. What will the genotype frequencies be among the offspring? Suppose instead that every individual mates with a first cousin. What will the genotype frequencies be among their offspring? Finally, suppose that after many generations of random mating, every individual in...

Why is it that lethal recessive alleles remain in the human gene pool, rather than just disappearing because of their unfavorable phenotype for homozygous recessives? Scenario: A sudden flood of a large area around the Mississippi River occurs. In some local populations of a species of insects, there is greater buoyancy and survival of some individuals due to having the double recessive genotype of a gene that allowed them to accumulate more lipids to float. A year after the flood,...
