Genetics

Two parrots have different parents. One has a blue tail and the other does not. Why do the parrots have different colored tails?

• Each parrot has different tail colors because different parents will have different color tails.

• Each parrot has different tail colors because they have different versions of the gene for tail color that connect together to make different tail colors.

• Each parrot has different versions of the gene for tail color. The genes are split inside one parrot and not the other.

• The parrot has different versions of the gene for tail color, this instructs for different proteins that connect in different ways to make different tail colors.
