Eye color is a polygenic trait. Height and skin color are also polygenic traits. If there is a vast variation in a trait, it's likely that it is polygenic.


Polygenic traits are those traits that are controlled by more than one gene. Such traits may even be controlled by genes located on entirely different chromosomes. Human height, eye and hair color are examples of polygenic traits. Skin color is another polygenic trait for humans and a variety of oth


Examples of polygenic inheritance in humans include height, eye color and skin color. Physical traits that have polygenic inheritance are influenced by more than one gene and typically display a continuous distribution, such as a range of heights. Polygenic traits do not have the classic phenotypic


A family trait is a genetic likeness that is passed through parents' genes to their children. Most specific traits are passed directly from one parent. Genetic disorders are also traits that can be passed from a parent to a child.


Biology, or the study of life, is important because it helps people to understand ourselves and the world people live in. Biology has several branches that specialize in certain areas of life. Some of these include genetics, immunology, physiology and ecology.


In psychology, Gordon Allport identified three types of personality traits: cardinal traits, central traits and secondary traits. While Allport's theory provides an open framework for psychoanalysis, other researchers, such as Raymond Cattell and Hans Eysenck, divided traits into objective opposites


Polygenic traits also have dominant and recessive alleles, but so many genes play a role in an organism’s phenotype for these traits that the final result is the sum of many complex interactions. It can be hard or impossible to figure out one gene’s effect on a polygenic trait.


Polygenic trait definition. Polygenic trait refers to a trait that is controlled by multiple non-allelic genes.These genes are called polygenes.They are a group of genes that when turned on, they are expressed as a unit. Each of them produces an effect that adds up to the trait.


Polygenic traits are quite different from the classical Mendelian trait in where we see that one gene controls one characteristic or one phenotype. Surprisingly, most traits in humans, and in fact most traits in most organisms, are polygenic. Mendelian traits, although we spend a lot of time talking about them, are really the exception.


Polygenic Inheritance Definition. Polygenic inheritance, also known as quantitative inheritance, refers to a single inherited phenotypic trait that is controlled by two or more different genes.. In a system which differs from Mendelian Genetics, where monogenic traits are determined by the different alleles of a single gene, polygenetic traits may display a range of possible phenotypes ...
