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 oranisms is likely to be

A

0.42

B

0.49

C

0.09

D

0.58

Text Solution

Verified by Experts

The correct Answer is:
A
`(p + q)^2 = p^2 + 2pq + q^2 = 1`
`MN = 2pq`
`= 2xx 0.7 xx 0.3 xx 100= 42%`
