Question

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

a woman who does not have hemophilia
a man who does not have hemophilia
a woman who has hemophilia
a man who has hemophilia

Answer 1

its a man who does not have hemophilia

Answer 2

The right answer is a man who does not have hemophilia

A male subject carrying the "h" gene of hemophilia, will express the disease (hemophilia).

A male subject carrying the normal "H" gene does not express the disease (healthy subject).

X-H Y ==> genotype of a normal male

X-h Y ==> genotype of a hemophiliac
