Polygenic definition, one of a group of nonallelic genes that together control a quantitative characteristic in an organism. See more.
Jul 31, 2017 ... Definition ... Polygenic traits are controlled by two or more than two genes ( usually by many different ... A phenotypic ratio where the effect of a single gene can be predicted would therefore not apply to polygene expression.
A "polygene” or "multiple gene inheritance" is a member of a group of non- epistatic genes that ... Traits with polygenic determinism correspond to the classical quantitative ... For example, they may be interested in knowing whether a phenotype is shaped by many independent loci, or by a few loci, and do those loci interact.
Nov 30, 2012 ... Are all people either short or tall? Unlike Mendel's peas, people do not all fall into two categories: short or tall. Most people, in fact, are ...
Because multiple genes are involved, polygenic traits do not follow Mendel's pattern of inheritance. Instead of being measured discretely, they are often ...
Traits that display a continuous distribution, such as height or skin color, are polygenic. The inheritance of polygenic traits does not show the phenotypic ratios ...
Looking at a real example of a human polygenic trait would get complicated, ... one of which makes pigment (the capital-letter allele) and one of which does not ..... Polygenic just means that there are multiple genes involved in a phenotype.
polygenic inheritance (multifactorial inheritance; quantitative inheritance) The determination of a particular characteristic, e.g. height or skin colour, by many ...
In order to properly understand the definition of a polygenic trait, also known as a ... This became a particularly relevant method as different alleles do not always ...
