In a population, autosomal dominant-recessive inheritance can be expressed by Hardy–Weinberg. The simple algebraic expression is:
p2+2pq+q2=1
where, p is the frequency of A = 0.6
q is the frequency of a = 0.4
2pq is the frequency of Aa (heterozygous individuals)
=2×0.6×0.4=0.48
Thus, the expected frequency of heterozygous individuals = 48%
