Question

The inheritance pattern for an autosomal dominant trait is shown in the pedigree. Shaded symbols represent individuals that express the dominant trait. Based on this pedigree, what are the most likely genotypes of individuals I-1 and I-2? I-1: aa I-2: Aa I-1: AA I-2: Aa I-1: Aa I-2: aa I-1: aa I-2: AA

Answer 1

The most likely genotypes for individuals I-1 and I-2 in this pedigree, based on autosomal dominant inheritance, are either AA or Aa.

Step-by-step explanation:

In this pedigree, individuals I-1 and I-2 are represented by the shaded symbols, indicating that they express the dominant trait. Based on the principles of autosomal dominant inheritance, individuals who express the dominant trait must have at least one dominant allele. Therefore, the most likely genotypes for individuals I-1 and I-2 would be either AA or Aa.
