Final answer:
The correct answer is B) 25% chance that a child (male or female) of a female carrier for hemophilia and a healthy male will have hemophilia. Male offspring have a 50% chance of having the disorder, while female offspring would be carriers or unaffected.
Step-by-step explanation:
The subject of this question is Biology, specifically focusing on genetics and the inheritance of X-linked recessive disorders like hemophilia. When a female carrier for hemophilia has a baby with a healthy male, there is a 50% chance that any male offspring will have hemophilia because they receive one X chromosome from the mother and a Y chromosome from the father. If the X from the mother carries the hemophilia gene, then the son will express the disorder because there is no corresponding allele on the Y chromosome that could mask the effect of the recessive allele.
Daughters have a 50% chance of being carriers like their mother because they will inherit one normal X chromosome from their father and potentially one with the hemophilia gene from their mother. Therefore, the correct answer is B) 25% likelihood that a child would have hemophilia, considering both sons and daughters. However, if only male offspring are considered, then the percentage would be C) 50%.
