What needs to happen for recessive traits to be observed in an organism?
ANEK [815]

Answer:

For recessive traits to be observed, dominant genes must be absent.

Explanation:

There are 3 possibilities for the genes: AA, Aa, aa.

in both AA and Aa, there is a dominant gene present. If a dominant gene is present, it will always show the dominant trait.

In aa, there is no dominant gene present, and there are only recessive genes. Because of this, the recessive trait is observed!
