Blue eyes are recessive in humans. If 20% of the population has blue eyes, what is the frequency of homozygous dominant individuals in this population?
a. 0.8
b. 0.45
c. 0.30
d. 0.55

The frequency of homozygous dominant individuals in this population is 0.55.

Explanation:

According to Hardy-Weinberg Equilibrium,

                                 p + q = 1

For the Homozygous recessive gene is given by ².

where, p represents the frequency of dominant gene.

           q represents the frequency of recessive gene.

                                   ² = 20 % = 20 / 100 = 0.2

                                   q =

                                   q = 0.45

                              p + q = 1

                                    p = 1 - q

                                       = 1 - 0.45

                                    p = 0.55.

the correct answer would be 6 feet.
