According to Hardy-Weinberg principle, the expected frequency of MN -blood group bearing organism is likely to be p2 + 2 pq + q2 = 1 0.49 + 0.09 + 2x = 1 0.58 + 2x = 1 2x= 1-0.58 =42 %

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

$42%$

$49%$

$9%$

$58%$

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

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
