Study the diagram above. It represents four people: two parents and their two children. Parents are indicated by the symbols in
the top row. Children are indicated by the symbols in the bottom row. Circles represent females and squares represent males.
In this family, only the daughter expresses a particular trait. The other members of the family (unshaded symbols) do not
express this trait. Could this trait be dominant, or is it recessive? How do you know?
