Question

36% of your study population are h recessive for fingernail growth rate. Using the Harvey Weinberg equilibrium equations (P+Q = 1 and P2+2PQ+Q2 = 1), calculate the frequency of h dominants and heterozygotes in your population.

Answer 1

frequency of h dominant = 16%

Frequency of heterozygotes = 48%

Step-by-step explanation:

The computation of frequency of h dominants and heterozygotes in your population is shown below:

Since it is mentioned that

q^2 = 36%

So q = 0.6

And

p + q = 1

So, the p is 0.4

Now the frequency of h dominant is

= p^2

= (0.4)^2

= 16%

And, the heterozygotes in the population is

= 2 × p × q

= 2 × 0.4 × 0.6

= 48%
