Question

4.
In a population with two alleles 'b' and 'B' having allele frequency 0.7 and 0.3 in Hardy-
Weinberg equilibrium, how many individuals in a sample of 250 can be expected to be
heterozygous (bB)?
52
105
0 21
O 42​

Answer 1

Heterozygous Bb=2pq

Here, q=b=0.7

P=B=0.3

2pq=2×0.3×0.7

=0.42

=0.42×250=105
