Question

"in a population of 100, 65 of the people are homozygous dominant and 15 are homozygous recessive. what is the genotypic frequency of the homozygous dominant population, heterozygous population and homozygous recessive population.

Answer 1

Its easy to get the genotypic frequencies as follows;

1.       Homozygous dominant;

65/100 = 0.65

2.       Homozygous recessive;

 15/100 = 0.15

3.       To get heterozygous population;

100 - (65 + 15) = 20
20/100 = 0.2
