Mark the genotypes which express hemophilia. (answer (s) can be more than 1)

XY^b

X^bY

YY^b

XX^b

X^bX^b

Option B and E

Explanation:

Hemophilia is a sex linked or X - linked recessive genetic disease. Both the X allele in a female must be hemophilic else the female would only be the carrier.

Let's say if the genotype of a female is XhXh, where Xh signifies affected allele then the female will be having Hemophilia

If any of the X allele in a female 's genotype is unaffected, then the female will be just a carrier. Thus, such a female would have XHXh, where XH signifies unaffected allele.

Like wise a affected male will have XhY genotype.

Thus, option B and E are correct.

the answer is YY^b, XX^b, X^bX^b, and X^by
