Question

part a
what type of trait is shown in the above chart?
a recessive
b dominant

Explanation:

In a pedigree, if a trait is dominant, it tends to appear in every generation. Looking at the given pedigree, the trait (represented by blue - colored symbols) is present in multiple generations without skipping. Recessive traits often skip generations as they require two copies of the recessive allele (one from each parent) to be expressed. Since the trait in the pedigree does not skip generations, it is more likely to be a dominant trait.

Answer:

B. dominant
