Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
What else can I help you with?
What controls a polygenic trait?
two or more genes
What kind of trait is present when many different genes different genes control a single trait such as skin color?
epistasis
What is it called when three or more contrasting genes control a trait?
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.
Multiple gene or polygenic inheritance occurs when two or more genes code for a single trait?
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.
In what are there more than two possible alleles for a trait?
gene therapy/ Polygenic trait
What is the difference between a single gene and a polygenics 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.
What is the difference between epistasis and polygenic inheritance in genetics?
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.
What is the difference between pleiotropy and polygenic inheritance?
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.
What kind of trait is present when many different genes control a single trait as a skin color?
polygenic
What is one difference between a single gene trait and a polygenic trait?
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.
What kind of trait is present when many different genes control a single trait such as skin color?
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.
True or false height is not a polygenic trait?
false, height is a polygenic trait
What controls a polygenic trait?
two or more genes
What kind of trait is present when many different genes different genes control a single trait such as skin color?
epistasis
When two or more sets of alleles affect the same trait in an additive fashion the trait is termed?
Yes, a single gene can affect many traits. this is called plieotropy
Define and distinguish between pleiotropy and polygenic inheritance?
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.
What occurs when a group of gene pairs acts together to produce a single trait?
Polygenic Inheritance
