1. There are two alleles at a locus: A and P. Assume these two alleles are in Hardy-Weinberg equilibrium. Assume also that Allele P has a frequency of exactly 1% in the population. Given this information, what is the frequency of AP heterozygotes in the population?

2. You are studying an allele A that governs parasite resistance in a large population of rabbits.

You observe that different combinations of A and a produce phenotypes that have different fitnesses due to differences in parasite resistance.

The fitness of AA is 0.38, the fitness of Aa is 0.38, while the fitness of aa is 0.24.

A allele starts at a frequency of 0.67.

Assuming Hardy-Weinberg equilibrium except for differences in selection, what will the frequency of A be in the next generation?

Answer #1

1)

1% indicate 1/100

frequency of allele P = 1/100 or 0.01

frequency of allele A = 99/100 or 0.99

frequency of heterozygote ( AP) 2pq = 2X 0.01X0.99

=0.0198

There are three different alleles at the same locus that contribute to blood type. A homozygote for AA will be type A, a homozygote for BB will be type B, and a homozygote for ii will be type O. Heterozygotes exist as well, where A is codominant with B (producing type AB), and both A and B are dominant to i. In a population, 4% are type O, and 1% of the individuals are homozygous for type A.

Recently, researchers found evidence that a single locus in the human genome (called CYP1A2) may affect how different people metabolize caffeine. Humans with two copies of the “fast” allele at this locus feel an immediate effect from caffeine that dissipates quickly. Humans with one or more copies of the “slow” allele experience a slower-building but longer-lasting effect after consuming caffeine. Research suggests that about 38% of the human population are homozygous fast metabolizers, 44% are heterozygotes, and 18% are homozygotes...

3) In general, p = allele frequency of the dominant allele and q = allele frequency of the recessive allele. Using the product and/or sum rule(s), use these variables (p and q) to determine the probabilities of an individual in the next generation being: a) Homozygous dominant (A dominant allele (A) AND another dominant allele (A))? b) Homozygous recessive (A recessive allele (a) AND another recessive allele (a))? c) Heterozygote (Aa OR aA)? 4a) In a population in Hardy-Weinberg equilibrium,...
