PATHOLOGY

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: -Three examples of polygenic traits in humans are height, skin colour and eye colour. These traits are governed by multiple genes.

Detailed explanation-3: -Polygenic trait: also called quantitative or complex trait, a polygenic trait is determined by several genes and/or regulatory loci.

Detailed explanation-4: -What are polygenic inheritance examples? Human phenotypes or human physical traits such as hair color, height, skin color, blood pressure, intelligence, autism, and longevity are some of the examples of polygenic inheritance.

Detailed explanation-5: -While Mendelian traits tend to be influenced by a single gene, the vast majority of human phenotypes are polygenic traits. The term polygenic means “many genes.” Therefore, a polygenic trait is influenced by many genes that work together to produce the phenotype.
