Question

In humans, the allele for hemophilia, h , is recessive. Which phenotype is displayed in an individual with the genotype X H Y?

a woman who does not have hemophilia


a man who does not have hemophilia


a man who has hemophilia


a woman who has hemophilia

Answer 1

It's definitely not the woman, so I'd say it's B. As the trait is recessive, a person who doesn't have hemophilia itself is likely to be able to pass it on to there children.

Answer 2

A man who does not have hemophilia

Step-by-step explanation:

Hemophilia is an X linked recessive disorder. Affected females are denoted by genotype Xh Xh while the normal but carrier females have genotype Xh X.

On the other hand, normal males are denoted by genotype XH Y. Here, presence of X chromosome with normal allele imparts no disease to the male.

The males with hemophilia have "h" allele on their X chromosome and are denoted by genotype Xh Y.
