Question

Why is hemophilia more common in males than in females?

A.hemophilia is more common in females
B.affected males only need to inherit one copy of the allele
C.hemophilia affects only males

Answer 1

the answer is C

Females can also have hemophilia, but this is much rarer.

Answer 2

The answer would be B.

Males are XY(have one X chromosome) so when it comes to x linked diseases they express everythinggg that is on that chromosome(they only need one copy). But females need 2 copies of the recessive allele in order to express it.
