Question

What type of traits are considered polygenic traits?

1) Traits affected by interactions among many genes
2) traits with multiple effects caused by a single gene
3) traits with more than two alleles in a population
4) Traits showing a blending of two phenotypes

Answer 1

Traits affected by interactions among many genes

Step-by-step explanation:

Characteristics that are polygenic are controlled by two or more major genes. The physical expression of these genes is not influenced significantly by environmental conditions. Polygenic traits are a type of discontinuous variation.
