Which of the following is defined as a gene that controls the appearance of a certain trait?

a) dominant
b) recombinant
c) recessive
d) mutated

A. Dominant

Explanation:

A dominant gene or allele is what determins the physical expression of a trait. A dominant allele masks recessive traits, which is why that even if it is combined with a recessive allele, the dominant trait is what is shown. For a recessive trait to appear, the organism should not have a dominant allele with it.
