Correct Answer

Explanation

Complementary gene interaction is a type of gene interaction where two genes work together to produce a trait. In this interaction, one gene controls the production of an enzyme that is necessary for the expression of the trait, while the other gene controls the production of a substrate that the enzyme acts on. The 9:7 ratio shows that 9 offspring have both dominant genes, while 7 have either one dominant or both recessive.
