Vedclass · Answer

(D) Albinism is an autosomal recessive disorder. Let the normal allele be $A$ and the albino allele be $a$.An albino father has the genotype $aa$. His daughter must inherit one $a$ allele from him,so her genotype is $Aa$ (carrier,as she is normal).She marries an albino man,whose genotype is $aa$.The cross is $Aa 	imes aa$.The possible genotypes of the offspring are $Aa$ (normal) and $aa$ (albino) in a $1:1$ ratio.Therefore,the ratio of their offspring will be $1$ normal : $1$ albino.

An albino father's daughter marries an albino man. What will be the ratio of their offspring?
