Hemophilia is an X-linked, recessive trait. The recessive allele for hemophilia is actually a mutated version of the normal alllele but it
can still be passed on through generations. Imagine a female has hemophilia; her genotype is XHXH. She is married to a man who
does not have hemophilia and yet all the male offspring will have hemophilia. Compare the cross you see here with the Mendelian
cross for attached earlobes: attached earlobes are a recessive, non-linked trait. How will the results of this cross vary from the
pedigree chart you see here?
