Please solve the following three problems

Dear student,
Please find below the answer:

4. If the carrier woman  (XhX) marries a normal male whose genotype would be XY, the nature of their children would be as follows:
  Xh X
X XhX (Carrier daughter) XX (Normal daughter)
Y XhY (Hemophilic son) XY (Normal son)

5. Thalassemia is an autosomal recessive disorder. If a thalassemic carrier man (say Rr) marries a woman who is also a carrier of thalassemia (Rr), 25% of their children will be affected by the disorder.

  R r
R RR (Unaffected child) Rr (Carrier)
r Rr (Carrier) rr (Affected child)

Please post rest of the questions in a separate thread.

Hope this clears your doubt.
