Question

Skin color in humans is a polygenic trait influenced by multiple genes. If a person inherits a mix of dominant and recessive alleles from their parents . which combination is most likely to result in medium skin tone? A) All dominant allelesB) All recessive allelesC) A mix of dominant and recessive allelesD) It cannot be predicted

Answer 1

C) A mix of dominant and recessive allelesIn humans, skin color is a polygenic trait, meaning it is influenced by multiple genes. Each gene has different alleles, which can be either dominant or recessive. When a person inherits a mix of dominant and recessive alleles from their parents, it is most likely to result in a medium skin tone. This is because the dominant alleles can mask the effect of the recessive alleles, leading to a range of skin tones rather than just the extremes.
