Question

111. Which one of the following is the most likely ratio of
blood groups (A:B: AB) among the progeny from
heterozygous parents with B and AB blood groups?
(a) 0.5 : 0.25 : 0.25
(b) 0.25 : 0.25 : 0.5
(c) 0.25 : 0.5 : 0.25
(d) 0:0.25 : 0.75​

Answer 1

Answer:

answer will be option C

Explanation:

IAIB = AB

IAI0 =A

IBIB = B

IBI0 = B

A : B : AB

1 : 2 : 1

Ratio of red blood groups (A : B : AB) in the progenies are = (1/4 : 2/4 : 1/4)

= 0.25 : 0.5 : 0.25
