In humans, albinism (unpigmented skin, hair, and eyes) is due to an enzymatic deficiency, and it is an autosomal recessive trait. Suppose that in a small country of one million people (“Generation 1”), there are 500 aa albinos and 9000 Aa heterozygous carries. If the Generation 1 follow the Hardy-Weinberg equilibrium?

a) then the number of homozygous aa albino individuals would be equal to P2

b) there were 500 albino individuals in generation one.

c) then the number of homozygous aa albino individuals would be equal to q2

d) there were 25 albino individuals in generation one.

Which of the following is the correct prediction about the hardy-weingburg equilibrium?
