If Two Different Alleles for the Same Trait Have an Equal

Question

If two different alleles for the same trait have an equal effect on the phenotype,the alleles are
A) codominant.
B) recessive.
C) epistatic.
D) incompletely dominant.

Accepted Answer

Codominance is when two different alleles for the same gene have equal effects on the phenotype when present in a heterozygous individual, resulting in both traits being expressed simultaneously. Therefore, if two different alleles for the same trait have an equal effect on the phenotype, they are codominant. The other options (B, C, D) do not fit the given scenario.
