Hemophilia A is a common disease in which the ability of the blood to clot is severely reduced, causing the sufferer to bleed severely from even a slight injury. It is carried as a recessive allele on the X chromosome. Below is a pedigree which illustrates the incidence of Hemophilia within a family over four generations. If we let "N" = normal clotting and "n" = hemophilia. What is the genotype of individual 2 in generation I?

-X^{N}X^{n}

-X^{n}X^{n}

-X^{n}Y

-X^{N}X^{N}

-Most likely X^{N}X^{N} but could also be X^{N}X^{n}

Hello

Haemophilia is a mendelian disorder

it is a autosomal recessive disorder which means for haemophilia to be shown it has to be in homozygous recessive order

for the first question the answer would be XN Xn because she is a carrier but not affected

for the second question opt 4 is right

for the third question option 4 is right

goodday:)
