Q. For the MN-blood group system, the frequencies of $M$ and $N$ alleles are $0.7$ and $0.3$, respectively. The expected frequency of $MN$-blood group bearing organisms is likely to be

Evolution

Solution:

According to Hardy-Weinberg principle, the expected frequency of $MN$ -blood group bearing organism is likely to be
$p^{2} + 2 pq + q^{2} = 1$
$0.49 + 0.09 + 2x = 1$
$0.58 + 2x = 1$
$2x= 1-0.58$
$=42\%$
