Question

Hair color is a trait that’s controlled by many genes working together. Each gene contributes to this trait only in a small proportion. Which pattern of inheritance is this?

codominance

incomplete dominance

multiple allele

polygenic inheritance

Answer 1

The correct answer should be polygenic inheritance

Most genes that affect the way a human being looks have been inherited in this way. Not only hair but also things like height and weight, eye color, and similar.

Answer 2

Answer: polygenic inheritance

Explanation:

Polygenic inheritance can be defined as the inheritance of several alleles which code for a specific physical characteristic such as eye color, skin pigmentation, hair color, shape of the body, weight and height. All these traits are controlled and expressed by the interaction of several alleles that code for a particular phenotype.
