Vedclass · Answer

(A) Albinism is an autosomal recessive disorder. Let the normal allele be $A$ and the albino allele be $a$. Since both parents are carriers,their genotype is $Aa$. When $Aa 	imes Aa$ are crossed,the offspring genotypes are $AA$ (normal),$Aa$ (carrier/normal),and $aa$ (albino) in a ratio of $1:2:1$. Each child is an independent event with a $25\%$ chance of being albino $(aa)$,a $50\%$ chance of being a carrier $(Aa)$,and a $25\%$ chance of being normal $(AA)$. Therefore,for any given child,there is a possibility of being normal,heterozygous (carrier),or albino. Thus,the first three children can be any combination of these genotypes/phenotypes.

Both parents are carriers for albinism. What will be the genotype/phenotype of the first three children?
