For a dominant/recessive trait, do the offspring of identical parents always look like the parents?
Mashcka [7]

Answer:

No, they don't always look like the parents.

Explanation:

They won't always look like the parents because from each parent, they will receive different dominant and recessive traits. In addition, certain traits skip generations or don't get passed down. For example, you can have 2 parents with red hair and have dark brown hair, but have a child who DOES have red hair.
