Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
two or more genes
epistasis
When three or more contrasting genes control a trait, it is called polygenic inheritance. This type of inheritance involves multiple genes interacting to influence a single trait, resulting in a continuous distribution of phenotypes in a population.
Polygenic inheritance occurs when a trait is controlled by two or more genes. Each gene contributes a small amount to the phenotype of the trait, resulting in a continuous range of phenotypic variations.
gene therapy/ Polygenic trait
A polygenic trait is a trait in which multiple sets of alleles are used to determine the trait, whereas in a single gene trait aka. a Mendelian trait, only one pair of alleles is used.
Epistasis is when one gene affects the expression of another gene, while polygenic inheritance involves multiple genes contributing to a single trait. Epistasis involves the interaction between genes, while polygenic inheritance involves the cumulative effect of multiple genes on a trait.
Pleiotropy refers to a single gene influencing multiple phenotypic traits, while polygenic inheritance involves multiple genes contributing to a single trait. Pleiotropy can lead to diverse phenotypic effects, while polygenic traits are often influenced by the additive effects of multiple genes.
polygenic
Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by mulitple genes. This information came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston.
Polygenic trait, where multiple genes contribute to the expression of a single trait like skin color. Each gene may have a small effect on the trait, and their combined influence results in a continuous range of variation.
false, height is a polygenic trait
two or more genes
epistasis
Yes, a single gene can affect many traits. this is called plieotropy
Pleiotropy occurs when a single gene influences multiple, seemingly unrelated traits or phenotypes. Polygenic inheritance, on the other hand, involves the combined effect of multiple genes on a single trait. In pleiotropy, one gene has multiple effects, whereas in polygenic inheritance, multiple genes each have a small additive effect on a trait.
