Answer :
Answer:
The correct answer is - 50% of children will have hemophilia and all will be male.
Explanation:
Hemophilia is a sex-linked recessive genetic disorder that occurs mostly in males due to the fact that to express this disease both the dominant copy of the gene should be absent. In males, there is only one X chromosome so the chances of being masked by the dominant allele are zero. While In women there are two X chromosomes so to express this disease both alleles need to be recessive.
Thus,
Hemophilic women marry (XhXh) with a normal man (XY)
Gametes will be - Xh, Xh and X, Y
Xh Xh
X XXh XXh
Y XhY XhY
Xh is here allele for hemophilic and X is normal, then there are 2 carrier women and two disease males will be produced.
