Question

match each type of complex inheritance to its description. not an example of complex inheritance multiple genes contribute to the expression of one trait. a single gene controls multiple traits. the alleles of one gene control the expression of a second gene. epistasis pleiotropy polygenic inheritance codominance

Explanation:

Epistasis is when one gene's alleles control another gene's expression. Pleiotropy is a single - gene controlling multiple traits. Polygenic inheritance is multiple genes contributing to one trait. Codominance is not related to the given descriptions.

Answer:

not an example of complex inheritance - codominance
Multiple genes contribute to the expression of one trait - polygenic inheritance
A single gene controls multiple traits - pleiotropy
The alleles of one gene control the expression of a second gene - epistasis
