Inheritance of a condition like phenylketonuria as an autosomal recessive trait

Vedclass · Answer

(B) $1$. In the given pedigree,both parents are unaffected (unshaded),but they have affected (shaded) offspring (both male and female).$2$. This pattern indicates that the trait is recessive because it skips generations and appears in the offspring of unaffected parents.$3$. Since both male and female offspring are affected,it cannot be $Y$-linked. If it were $X$-linked recessive,an affected daughter would require her father to be affected,which is not the case here.$4$. Therefore,the trait must be autosomal recessive. Phenylketonuria is a classic example of an autosomal recessive metabolic disorder.$5$. Thus,the pedigree represents the inheritance of a condition like phenylketonuria as an autosomal recessive trait.
