You observe a population of three-toed frogs that lives in the cloud forests of Panama. In this population, you observe the foll
goblinko [34]

Answer:

0.1460

Explanation:

Total population size= 411 + 911 + 800 = 2122

Let's assume that the population is in Hardy Weinberg Equilibrium.

Under these conditions, frequency of recessive allele (a)= 911 x 2 + 800 / 2122 x 2   = 2622/4244= 0.6178 .

This is because each homozygous recessive genotype has two copies of the recessive allele while each heterozygous dominant genotype has one copy of the recessive allele.  

For this population to be under Hardy Weinberg Equilibrium, frequency of dominant allele (A) = 1- 0.6178= 0.3822

Frequency of homozygous dominant genotype (AA) = 0.1460
