Q. A gene locus has two alleles A, a. If the frequency of dominant allele A is 0.4 then what will be the frequency of homozygous dominant, heterozygous and homozygous recessive individuals in the population ?
A) 0.36 (AA); 0.48 (Aa); 0.16 (aa)
B) 0.16 (AA); 0.24 (Aa); 0.36 (aa)
C) 0.16 (AA); 0.48 (Aa); 0.36 (aa)
D) 0.16 (AA); 0.36 (Aa); 0.48 (aa)
Explanation
[Solution] p = 0.4, q = 0.6: $p^2 = 0.16$, $2pq = 0.48$, $q^2 = 0.36$. Answer (3).
