A man who has type B blood has children with a woman who has type A blood. A. If they are both heterozygous for this trait, pred
Ivenika [448]

Answer:

The possible blood types of their children are: type AB (iAiB), type A (iAi), type B (iBi), type O (ii)

Explanation:

Blood type in humans is controlled by a gene with multiple alleles. Alleles iA and iB are dominant over allele i but co-dominant. The following blood types are encoded by the following alleles:

Blood type AB - iAiB

Blood type A - iAiA or iAi

Blood type B - iBiB or iBi

Blood type O - ii

According to this question, a man who has type B blood has children with a woman who has type A blood. They are both heterozygous, meaning that the man's genotype is "iBi" while the woman's genotype is "iAi". Both parents will produce gametes as follows:

iBi = iB and i

iAi = iA and I

Using these gametes in a punnet square (see attached image), the following possible blood types are produced in the offsprings:

- type AB (iAiB)

- type A (iAi)

- type B (iBi)

- type O (ii)
