A trait that is influenced by two or more genes, such as height or skin tone, is referred to as a polygenic trait.
Polygenic traits do not follow the laws of Mendelian inheritance since several genes are involved.
Multifactorial traits are many polygenic qualities that are additionally influenced by the environment.
There are relatively few people in the population who are at the minimum or maximum heights, and the majority of the population is in the middle height range, forming a bell-shaped distribution of height.
The majority of polygenic variables, including features of fingerprint patterns, blood pressure, and body weight, likewise plot as bell-shaped curves.
Mendel's groundbreaking research on genetic inheritance concentrated on features that resulted from a single gene, but subsequent investigations, such as genome-wide association studies, have shown that many human traits are the result of the collaboration of several gene products.
A polygenic (or "many genes") characteristic is one in which several genes interact to affect phenotype.
Human height is a prime example of a polygenic characteristic. Numerous loci are connected to the variation in human height.
