Question

A man with type A blood marries a woman with type B blood. Their child has type O blood. What are the genotypes of these three individuals? What genotypes, and in what frequencies, would you expect in future offspring from this marriage?

Accepted Answer

Hi everyone here we have a question telling us to assume that a mother has type a blood AO genotype and a father has Type B. V. O. Genotype. What will be the probability of the pair of producing a Type O offspring? So let's make our punnett Square. So we have I A I. O I B I. O. And that gives us I A I B I B I O I A I O I O I O. So type Io IO is blood type O. And looking at our opponent square, we see that 1/4 of our offspring is io io. So our answer here is C. 25%. Thank you for watching. Bye.
