What are the allele frequencies for a population if you have

What are the allele frequencies for a population if you have: 32 AA individuals 40 Aa individuals 28 aa individuals

AA (p²) = 32/100 = 0.32

Aa (2pq) = 40/100 = 0.4

aa (q²) = 28/100 = 0.28

Thus, p2 + 2pq + q2 = 1.

Now calculate the frequencies of the “A” and “a” alleles in this population:

• p = f(AA)+1/2f(Aa) = Frequency A

• q = f(aa)+1/2f(Aa) = Frequency a

ALLELE FREQUENCIES:

Freq of AA = p = p² + 1/2 (2pq) = 0.32 + 1/2 (0.4) = 0.32 + 0.2 = 0.34

Freq of aa = q = 1-p = 1 - 0.34 = 0.66
