Two non-allelic genes produce new phenotype when present together but fail to do so independently are called?

1. Epistasis
2. Polygenic
3. Non-complimentary genes
4. Complimentary genes

Correct answer: Complimentary genes

Solution

Complementary genes are non-allelic genes that interact so a new phenotype appears only when both dominant alleles are present together. If either gene is missing, the trait does not develop independently.
