You are studying a population of 1000 skunks (which are diploid). You sample alleles at two genetic loci, A and B. The A gene has two alleles A and a, and B has two alleles B and b. The frequency of the A, a, B, b alleles are p, q, r, s respectively, so that p = 0.2, q = 0.8, r = 0.3, s = 0.7.   1) Calculate the expected genotype frequencies of all possible genotypes under Hardy-Weinberg equilibrium.  2) Calculate the expected haplotype frequencies of all possible haplotypes assuming the two loci are unliked.

Question

You are studying a population of 1000 skunks (which are diploid). You sample alleles at two genetic loci, A and B. The A gene has two alleles A and a, and B has two alleles B and b.

The frequency of the A, a, B, b alleles are p, q, r, s respectively, so that p = 0.2, q = 0.8, r = 0.3, s = 0.7.

 

1) Calculate the expected genotype frequencies of all possible genotypes under Hardy-Weinberg equilibrium. 

2) Calculate the expected haplotype frequencies of all possible haplotypes assuming the two loci are unliked.
