f a male has hemophilia (XhY), where did he inherit the hemophilia allele from?
Added by Edward M.
Step 1
Hemophilia is a genetic disorder that is typically inherited in an X-linked recessive pattern. This means that the gene responsible for hemophilia is located on the X chromosome. Show more…

A couple has a son named Jay. Jay has hemophilia, a disease that prevents him from being able to produce blood clots. Hemophilia is caused by a malfunctioning allele on the X chromosome. Since Jay has hemophilia, which of the following must be true? Jay's father has hemophilia. Jay's mother is heterozygous for hemophilia or has hemophilia. Jay inherited an X chromosome from his father. None of these.

Hemophilia is a hereditary disease that prevents a person's blood from clotting correctly. The gene responsible for blood clotting is located on the X chromosome of the sex chromosome pair (X and Y). This is called X-linked inheritance. The dominant gene is H, and the recessive gene causing hemophilia is h. Anyone with the dominant gene will not inherit hemophilia. The mother (X^h, X^H) and father (X^H and Y) have children X^H X^H, H^H X^h, X^H Y, and X^h Y. What are the chances of a child having hemophilia? Why?

Hemophilia is an X-linked disorder that affects the body’s ability to create blood clots. The allele for normal blood clotting, XH, is dominant over the allele for hemophilia, Xh. An unaffected female that is not a carrier mated with an affected male. Which of the following rows identifies the possible genotypes of the offspring? Select one: a. Female Male XHXH and XHXh XHY and XhY b. Female Male XHXh XHY c. Female Male XHXh XHY and XhY d. Female Male XHXH and XHXh XHY
