Hemophilia is an x-linked recessive disorder (xh) that is passed through generations and can be traced by using a pedigree.

based on the pedigree that is shown, which describes john?

a. carrier for hemophilia

b. expresses hemophilia

c. does not have hemophilia

d. expresses hemophilia and died of complications

The correct answer is C. does not have hemophilia

Explanation:

In the given pedigree John has an XH chromosome, which means that he has the dominant chromosome. As males have one X, they can either be affected or unaffected. So, in this case John could not be carrier. Also, the Dominant chromosome is fully functional and does not show the characters of the disease, so, John would be free of hemophilia.

i believe it is c: genes for body color and wing size are inherited separately from each parent.
