Given

OPTION = A

0.09

Answer 2

Answer:

E= .7 Black wool frequency

Explanation:

q^2 = 0.09

p^2 + 2pq = 0.91

q = 0.3

p = 1 - q = 0.7

Therefore, the black wool frequency is .7  

Allele frequency or what we call as  gene frequency means the relative frequency of an allele at a particular position in a population. It is usually represented in percentage. It is a fraction of chromosome which a population carry.
