Answer 5

i can't give you an answer, but i can tell you to write the possible genotypes in the options.

for example, "In order for a female offspring to be a hemophiliac, her father must be a hemophiliac"

Females have two X chromosomes, and thus the genotype she could have if her father gave her the hemophiliac allele, she'd have \(X^hX\) or \(X^hX^h\) depending on the allel the mom gave.

To be a hemophiliac you need both alleles to be \(X^h\), thus this is not the answer.

Answer 6

wait
isn't this the answer then ?
becuase u said the combination can be XhX or XhXh

Answer 7

and XhXh is hemophilia , right @aaronq
