Question

A researcher samples gametes in two separate generations and observes the following results:

Generation 0:

Number of GH = 195

Number of Gh = 45

Number of gH = 30

Number of gh = 30

Generation 1:

Number of GH = 192

Number of Gh = 48

Number of gH = 33

Number of gh = 27

What will be the frequency of the h allele at equilibrium?

Answer 1

Allele frequency = number of the allele/ total number of alleles

Allele frequency remain unchanged if the population is in equilibrium

Hence frequency of h alelle is same in generation 0 and generation 1

frequency of h allele in generation 0 is= (45*2)+(30*2)/(300*2)

= 0.25

Frequency of h allele in generation 1 is = (48*2)+(27*2)/(300*2)

= 0.25
