How many heterozygotes are expected in a population of 30 when the allele frequencies are known to be p = 0.5 and q = 0.5?

Let’s say that in seals, the gene for the length of the whiskers has two alleles. The dominant allele (W) codes for long whiskers and the recessive allele (w) codes for short whiskers. a. What percentage of offspring would be expected to have short whiskers from the cross of two long- whiskered seals, one that is homozygous dominant and one that is heterozygous? [blank1] b. If one parent seal is pure long-whiskered and the other is short-whiskered, what percentage of offspring would have short whiskers? [blank2]      

AA Aa aa 85 85 70 % survival relative fitness What is the relative fitness of the homozygous recessive genotype in this example?

Assumes that most organisms have a large genetic load and sex works to remove mutations of small effect [one] Sex works to mask recessive mutations [two] Recombination during sex produces new combinations to generate new diversity [three]
