1 Answer

2

Answer:

The correct answer would be - 0.1 a, 0.9 A

Explanation:

The initial population of the colonist had free earlobes which are represented by A here as it is dominant and attached is represent by a. purebred dominant would have AA.

Frequency of allele A =

8 pure dominant and 2 heterozygous dominant presents in the population

So, frequency of A allele = 8 x 2 + 2 / 20

= 18/20

= 0.9

As we know

p+q=1;

frequency of allele "a" = 1-p

= 1-0.9

= 0.1
