In a population of manatees in Florida there are two possible alleles for hide color. The allele for gray hide color, G is dominant over the allele for white hide color, g. In this population, assume there are 800 G alleles and 200 g alleles. Use the Hardy-Weinberg equation to predict the expected percentage of individuals with white hides in the next generation.

Solution

The allelic frequency of G allele is 0.8. ( This is p in hardy weinberg equation)

The allelic frequency of g allele is 0.2 ( This is q in hardy weinberg equation)

p² + 2pq +q² = 1

So the frequency of individuals with gg white hide color is q² = 0.2 * 0.2 = 0.04

0.04 is the frequency of white hide color individuals
