The synthesis (S)
The second gap (G2)
M

A cell can be defined as simplest, basic, functional and structural unit of life

One parent has type A blood and the other has type B. What are their genotypes if they produced children whose blood types were

zhenek [66]

Answer:

iAiA and iBiB

Explanation:

Blood type in humans is controlled by a gene with three alleles namely: iA, iB, and i. Alleles iA and iB are dominant over allele 'i' but codominant. The following are the allelic combinations of the genotype and the resulting blood types:

iAiA or iAi - type A

iBiB or iBi - type B

iAiB - type AB

ii - type O

According to this question, one parent has type A blood and the other has type B. If all the offsprings of these parents have blood type AB, this means that the parents must have a genotype of iAiA and iBiB respectively.
