Vedclass · Answer

(B) In the given pedigree chart,the disorder is autosomal recessive. Individuals in generation $II$ are affected (shaded),meaning they must have the genotype $aa$. Since the parents in generation $I$ are unaffected but have affected children in generation $II$,both parents must be carriers of the recessive allele. Therefore,the genotype of the parents in generation $I$ must be $Aa$ and $Aa$.

Identify the genotype of the first generation $(I)$ for an autosomal recessive disorder based on the provided pedigree chart.
