Q. In Hardy-Weinberg law the homozygous dominant alleles, homozygous recessive alleles and heterozygous alleles are represented by I II III
A) $p^{2}$ $q^{2}$ 3pq
B) $p^{2}$ $q^{2}$ 2pq
C) $a^{2}$ $p^{2}$ 2pq
D) $q^{2}$ 2pq $p^{2}$
Explanation
In Hardy-Weinberg law I. Homozygous dominant alleles $= p^{2}$ II. Homozygous recessive alleles $= q^{2}$ III. Heterozygous alleles $= 2pq$ $(p + q)^{2} = p^{2} + q^{2} + 2pq$
