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.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
