Detailed explanation-1: -A polygenic trait is a characteristic, such as height or skin color, that is influenced by two or more genes. Because multiple genes are involved, polygenic traits do not follow the patterns of Mendelian inheritance . Many polygenic traits are also influenced by the environment and are called multifactorial.
Detailed explanation-2: -What is a polygenic trait? A trait that is controlled by a single gene. A trait that is controlled by a polygene. A trait that cannot be determined genetically. 2.
Detailed explanation-3: -The term polygenic means “many genes.” Therefore, a polygenic trait is influenced by many genes that work together to produce the phenotype. Human phenotypes such as hair color, eye color, height, and weight are examples of polygenic traits.
Detailed explanation-4: -1. Pleiotropy is the regulation of multiple traits by a single gene. Polygenic inheritance refers to a trait being controlled by multiple genes. 2. Pleiotropy has 2 or more than 2 genotypic outcomes.
Detailed explanation-5: -1) Multiple alleles refer to a series of three or more alternative forms of a gene. 1) A polygenic trait is a trait controlled by a group of non-allelic genes. 2) Only two types of alleles are present in an individual; several alleles can be found in the population. 2) All polygenes can be found in each individual.
