brown eyes (B)are dominant over blue eyes (b).A heterozygous brown eyed man marries a heterozygous brown eyed female,.what are the possible genotypes and phenotypes? i got 50 brown eyes 50 blue eyed.genotype of male is BB female bb phenotype of males 50% and female 50%

OpenStudy (shrutipande9):

see first of all the problem does not say that the trait is sex linked..so u cannot say that a boy will have blue eyes or brown eyes...sex is not linked with colour of eyes... now can u tell me what genotypes of parents did u take?

OpenStudy (anonymous):

but if they asked that it would be right though?

OpenStudy (shrutipande9):

no no...if they say that eye colour is linked to the X or Y chromosome then u can say whether it would be a boy or a girl...otherwise no...can u tell me d genotype of parents?

OpenStudy (anonymous):

it is Bb in both parents

OpenStudy (shrutipande9):
