Select the correct answer.
In chickens, a flat single comb is a recessive trait, while the short, thick rose comb is dominant. In a particular population of chickens, 45 are
homozygous for the dominant trait, 30 are heterozygous dominant, and 25 have the recessive trait. Which expression is the correct way to
calculate the frequency of the recessive allele?
​

Respuesta :

Allele frequency is used to display the genetic diversity of a species population .

Explanation:

To calculate the frequency of the recessive allele we use the  

THardy-Weinberg equation

p² + 2pq + q²

p+q=1

p is the frequency of the homozygous dominant genotype

q is the frequency of the homozygous recessive genotype

2pq is the frequency of the heterozygous genotype.

Total number of individuals = 45 + 30+ 25 = 100

So, the frequency of recessive trait = 25/100 =0.25.

Thus, the value of q² = 0.25

So, q would be equal to square root of 0.25 which comes out to be 0.5

80/200
