Why would it be wise for a woman carrying the hemophilia gene to keep her son from being circumcised?
because the probability of hemophilia would be 1: 4
because the probability of hemophilia would be 1: 2
because the probability of hemophilia would be 100%

Because the probability of hemophilia would be 1:4

Explanation:

Hemophilia is a disease that comes with a sex chromosome (pair 46).

It is a recessive allele associated with chromosome X, women have two X chromosomes they can carry it, but they don't have it because they have another dominand allele non-hemophilic.

If you draw a Punnet square with a non-hemophilic father and a carrying mother, you'll found you have 1:4 chances of having a baby boy with hemophilia.

Carrying mother = X(H)X(h)

Father = X(H) Y
