(C) Haemophilia is an $X$-linked recessive disorder.Let $X^h$ be the allele for haemophilia and $X$ be the normal allele.The genotype of a haemophilic man is $X^hY$.The genotype of a carrier woman is $X^hX$.When they cross $(X^hY 	imes X^hX)$,the possible genotypes of the offspring are:$X^hX^h$ (Haemophilic daughter)$X^hX$ (Carrier daughter)$X^hY$ (Haemophilic son)$XY$ (Normal son)Out of the two possible female genotypes ($X^hX^h$ and $X^hX$),one is haemophilic $(X^hX^h)$.Therefore,the probability of having a haemophilic daughter is $1/2$ or $50\%$.

If a haemophilic man marries a woman carrier (heterozygous) for haemophilia,what would be the possibility that their daughter would be haemophilic (in $\%$)?
