Answer:
Number of heterozygous population 64
Explanation:
Given data:
Total population of chicken 200
Number of chicken having featherless legs 128, that represent q2 (as they are homozygous recessive)
Total number of chickens = 200
Therefore, the value of [tex]q^2 = \frac{128}{200} = 0.64[/tex]
[tex]q^2 = 0.64[/tex]
so q = 0.8, and
p = 1 - q
= 1 - 0.8 = 0.2
The frequency of[tex] 2pq = 2 \times 0.8 \times 0.2 = 0.32[/tex]
Therefore, Number of heterozygous population[tex] = 0.32 \times 200 = 64[/tex]
