Pedigree analysis of a autosomal dominant trait

The trait is present in every generation of the lineage. Affected males (e.g.,
I-1) and affected females (e.g., II-4) both pass the trait on to half of their sons and daughters, in equal proportions.

Homework: Write out the genotypes of every individual in the tree.
