Question

13 the diagram shows a pedigree from a recessive inherited trait. pedigree for recessive trait key unaffected male affected male unaffected female affected female if h represents the dominat allele h represents the recessive allele, what are the genotypes of the parents shown in the pedigree? a hh and hh b hh and hh c hh and hh d hh and hh

Explanation:

Step1: Analyze the trait inheritance

Since the trait is recessive, an affected individual (like the daughter in the pedigree) must have the genotype \( hh \).

Step2: Determine the parents' genotypes

Parents are unaffected but have an affected offspring. For recessive traits, if two unaffected parents have an affected child, both parents must carry the recessive allele. So, the parents' genotypes are \( Hh \) (heterozygous) each.

Answer:

A. \( Hh \) and \( Hh \)
