What are the observed and expected heterozygosity in a population that has three genotypes with the following occurrences: f(A1A1) = 100, f(A1A2) = 25, f(A2A2) = 100
What will be an ideal response?
ANS:
Observed heterozygosity = 25/225 = 0.1111
Expected heterozygosity :
f(A1) = p = (2*100 + 25)/450 = 0.5
f(A2) = q = (2*100 + 25)/450 = 0.5
Expected heterozygosity = 2pq = 2*(0.5)*(0.5) = 0.5
