Question

If a person with o blood type produces offspring with a person with b blood type, then what percentage of their offspring will be type o in the best case scenario?

Answer 1

Answer:

In humans, blood group is determined by three alleles $I^{A}$, $I^{B}$, and $i$.

$I^{A}$ and $I^{B}$ are co-dominant whereas $i$ is recessive to other two.

Thus, if a person with blood group O produces offspring with blood group B then the other parent must contain $I^{B}$ allele.

The genotype of other person can be $I^{A}I^{B}$, $I^{B}I^{B}$, or $I^{B}i$.

There is only one condition in which the person can have offspring with blood group O that is, when the other parent is $I^{B}i$.

In this condition, the probability of an offspring to have blood group O is 50%.

In other conditions, the probability of an offspring to have blood O is 0%.

Answer 2

Maybe 50 percent is the answer
