In humans, brown hair is dominant and blond hair is recessive. Only 2% of people have red hair, and in order to receive it, both parents must pass the allele on to their offspring. What does this imply about red hair? (1 point)

Question

It is sex-linked.

It is recessive.

It is dominant.

It is codominant.

Answer 1

The correct implication about red hair is that it is recessive. Since both parents must pass the allele for red hair for a child to have red hair, this indicates that the allele is not expressed in a single copy, meaning it is recessive.
