Is the “extra finger” trait dominant or recessive? How do you know?

Sagot :

Answer:

It is recessive.

Explanation:

Having an extra finger, also known as polydactyly, is relatively rare, and people with polydactyly are unlikely to have children with the trait unless both the mother and father both have it, making it a recessive trait.
