In humans, the allele for normal blood clotting, H, is dominant to the allele for
hemophilia, h. This is a sex-linked trait found on the X-Chromosome. A woman
with normal blood clotting has four children, a normal son, a hemophiliac son, and
two normal daughters. The father has normal blood clotting. What is the
phenotype of mom?
HURRY PLEASE!!!!

Answer:

If sons are affected by the X-linked traits, then they're automatically going to have it because they only have one X and so it has to show. Females, however, have 2 X's and if they get one affected one and one unaffected one, then they're not going to get the trait (if its recessive)

-Because the mom is normal, that means that she has XHXh, and the dad has to have XHY. Their four children would have XHY, XhY, XhXH, and XHXH
