In sheep, white vs yellow body fat is determined by a single pair of autosomal alleles. In a large, randomly mating flock, 23 pe
Drupady [299]

Answer:

Option A , The allele for yellow is dominant to white

Explanation:

It is given that 23 percent of the sheep have white fat and 77 percent have yellow fat.

Thus, it is clear that sheeps with yellow fat is a dominant characteristics.

Usually, the frequency of homozygous recessive allele in a given population is represented by  q^2

and here q^2 = 0.23

Frequency of allele for white fat = q = \sqrt{0.23} \\q= 0.479

While frequency of homozygous dominant allele and heterozygous dominant allele is represented by p^2+2pq\\

And here p^2+2pq = 0.77

Allele for yellow fat = 1-q\\= 1-0.479\\= 0.521

Hence, option A is correct.
