Question

The a, b, o blood groups in humans are determined by multiple alleles in which Ia and Ib are dominant and both are dominant io.

If a woman with AB and a male with O blood had children, what is the probability that their first child would have type A?

Answer 1

The probability that their first child would have type A is 50%

Step-by-step explanation:

The Woman with blood group AB has genotype A/B

The Male with blood group O has genotype 0/0, blood group

Using plunnet square as seen in the attachment

So 50% blood group A, 50% blood group B.
