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?

The correct answer would be 0.5

The same can be explained with the help of Hardy-Weinberg equation

p² + q² + 2pq = 1

p + q = 1 Where,

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

the electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, x-rays, and gamma-rays.

the answer is "a.) well–developed vascular system."
