1) Suppose that a certain population of 100 individuals possesses two alleles (A and B) at a certain locus, and initially consists of the following numbers of genotypes: AA = 9, AB = 42, BB= 49.

a) Calculate the initial frequencies of alleles A and B.

b) Now suppose that 16 individuals with genotype BB do not survive to reproduce. Calculate the new allele frequencies among the remaining individuals that do reproduce. Assuming that these remaining individuals mate randomly, calculate the new genotype frequencies in the next generation. Use the following headings to organize your calculations.

14A. Suppose a population of flour beetles has 10,000 individuals. There are two alleles possible for the gene that determines body color: red (B), and black (b). BB and Bb beetles are red, while bb individuals are black. Assume the population is at Hardy–Weinberg equilibrium, with equal frequencies of the two alleles. What would be the expected frequency of red beetles? 14B. What would be the expected frequency of black beetles in the population as described in A? 14C. Assuming...

A gene in a randomly-mating population has two alleles (A,a), and 1 in 400 individuals in the population is homozygous recessive (aa). Calculate the frequency of heterozygotes (Aa) in the population.

You are studying a population of 100 lizards that has two alleles at a locus for skin color, blue (B) and green (G). There are 30 individuals with the BB genotype, 30 individuals with the BG genotype, and 40 individuals with the GG genotype. (a) What are the allele frequencies of B and G in the starting population? Show your calculations. (b) Is this population in Hardy-Weinberg equilibrium? Show your calculations.

1 - A population that is at equilibrium has two alleles, A and a. The frequency of the recessive allele a is 0.3. What is the frequency of individuals that are homozygous recessive? 2 - A population that is at equilibrium has two alleles, A and a. The frequency of the dominant allele A is 0.3. What is the frequency of individuals that are homozygous recessive?

Let A and B represent two variants (alleles) of the DNA at a certain genome locus...

Let A and B represent two variants (alleles) of the DNA at a certain genome locus (chromosome location). Assume that 40% of all the alleles in a certain population are type A and 30% are type B. The locus is said to be in Hardy-Weinberg equilibrium if the proportion of organisms that are of type AB is (0.40)(0.30) = 0.12 (in other words, alleles A and B are independent). In a sample of 300 organisms, 42 are of type AB....

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.

Suppose that there are two individuals in an economy, A and B, and that their utility possibility set is given by uB = 400 − 0.01u2A. Consider the point (uA,uB) = (100,300), is this point Pareto Efficient? Explain. Determine a linear social welfare function that has the point (100,300) as its maximum. Hint: the slope of the utility possibility frontier is given by −0.02uA. Start by determining the isowelfare line that goes through (100, 300).

(Show all work for credit) A population is in Hardy-Weinberg equilibrium with two alleles, B and B at a frequency 0.8 (B) and 0.2 (b). Allele B results in blue colored flowers and is dominant to the allele b which results in white flowers. I. Find the percentages for each genotype for the following generation II. Calculate the percentage of each phenotype III. Calculate the allele frequency in the new generation

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...
