what is the probability that a female child of charles and marie would suffer from hemophilia?
what is the probability that a female child of charles and marie would suffer from hemophilia?
Answer
Explanation:
Step1: Identify the genotypes of parents
Charles has genotype $X^{H}Y$ and Marie has genotype $X^{H}X^{h}$.
Step2: Determine possible genotypes of female offspring
The possible genotypes of female offspring are obtained from the cross. The cross of $X^{H}Y$ and $X^{H}X^{h}$ gives two possible genotypes for female offspring: $X^{H}X^{H}$ and $X^{H}X^{h}$.
Step3: Recall the inheritance pattern of hemophilia
Hemophilia is an X - linked recessive disorder. A female needs to have two recessive alleles ($X^{h}X^{h}$) to be affected.
Step4: Calculate the probability
Since none of the possible genotypes for female offspring of Charles and Marie is $X^{h}X^{h}$, the probability is 0.

0
