A region of a chromosome that contains one or more genes that affect a trait is called a quantitative trait locus. Polygenic inheritance means that the transmission of a trait is governed by two or more genes. If the environmental effect on a trait is relatively low then the distribution of phenotypes is more closely correlated with their ______. In general the more genes that are involved in the development of a trait the ______ the number of phenotypic classes that can occur.

Phenotypes are generally a product of: two or more genes in combination with each other. the genotype in combination with the environment. pleiotropic effects of a single gene. incomplete dominance. multiple alleles at the same gene locus.

Polygenic inheritance Select all that apply: Traits that are determined by the amount of copies of a gene. Traits that are determined by the number of trinucleotide repeats in a gene. Traits that are determined by multiple genes. Human eye color is an example of a trait with polygenic inheritance. Hemophilia is an example of a trait with polygenic inheritance. Huntington's disease is an example of a trait with polygenic inheritance.
