Question

which type of traits vary quantitatively due to the interaction of multiple genes?
polygeneic
codominant
incomplete dominant
dominant

Explanation:

Polygenic traits are determined by the interaction of multiple genes and show continuous quantitative variation. Codominant, incomplete - dominant, and dominant traits are related to allele - interaction patterns for single - gene inheritance and do not typically show the quantitative variation due to multiple - gene interaction like polygenic traits.

Answer:

A. polygenic
