- Making the world better, one answer at a time. Coat color and pattern is a polygenic trait, meaning it is controlled by more than one gene or gene complex. A dog with the gene for black color expression may also have the gene for suppression of black and so have a red or yellow coat. Polygenic traits are [characteristics of organisms that are] …  influenced by several genes.    So multiple alleles are more than two alleles for one trait, and  polygenic traits are one trait that is influenced by mulitple  genes.

Polymorphism (biology) An example of a botanical genetic polymorphism is heterostyly, in which flowers occur in different forms with different arrangements of the pistils and the stamens. The system is called heteromorphic self-incompatibility, and the general 'strategy' of stamens separated from pistils is known as herkogamy. Genetic polymorphism is the simultaneous occurrence in the same locality of two or more discontinuous forms in such proportions that the rarest of them cannot be maintained just by recurrent mutation or immigration, originally defined by Ford (1940).

Polygenic trait A trait that is controlled by a group of nonallelic genes. Supplement. Polygenic traits are controlled by two or more than two genes (usually by many different genes) at different loci on different chromosomes. These genes are described as polygenes.Examples of human polygenic inheritance are height, skin colour and weight. Polygenes allow a wide range of physical traits. For instance, height is regulated by several genes so that there will be a wide range of heights in a population.Word origin: poly = many + genic = of genes.hese genes are described as polygenes.

Human Physiology/Genetics and inheritance Polygenic traits are traits determined by the combined effect of more than one pair of genes. Human stature is an example of this trait. The size of all body parts from head to foot combined determines height. The size of each individual body part are determined by numerous genes.

- A - Many of the traits displayed in nature are polygenic. In humans, traits such as height, weight, skin pigmentation, and hair color are polygenic. In fact, many of your traits are polygenic. All these traits are controlled by the interaction of several genes.

multifactorial Definition of multifactorial 1: caused or marked by a polygenic mode of inheritance dependent on a number of genes at different loci The essence of multifactorial (polygenic) inheritance is that a single component of the phenotype (a single character) can be controlled by several independent gene loci. —Ernst Mayr ; also: caused by or dependent on the interaction of multiple genes combined with one or more environmental factors

-     Coat color and pattern is a polygenic trait, meaning it is controlled by more than one gene or gene complex.ultiple alleles are genes that have more than two alleles. An  example of this would be blood types, with ABO as three separate  alleles.   Polygenic traits are traits … whose phenotype rely on alleles from  different genes.

Understanding Polygenic Traits Polygenic Trait Aspects. Polygenic trait molding is done mostly with the environment and genes. More than one gene determines these traits, with each gene giving a small, yet additive effect. Multifactorial traits do not exhibit Mendelian ratios, and are determined between genes, or a gene, and the environment.olygenic Trait Aspects.

Which type of traits vary quantitatively due to the interaction of multiple genes? The answer is polygenic traits. Polygenic traits are determined by an interaction of multiple genes. As the name suggests, poly (Greek) means many, thus, polygenic means many genes. Many genes interact and together influence some phenotypic trait. Quantitative phenotypes are usually attributed to the polygenic effects.

What is a Polygenic Inheritance? The term “polygenic inheritance” is used to refer to the inheritance of quantitative traits, traits which are influenced by multiple genes, not just one.In addition to involving multiple genes, polygenic inheritance also looks at the role of environment in someone's development.or example, sickle cell anemia is a form of pleiotropy, caused by a distinctive mutation in one gene which leads to a host of symptoms. In addition to causing mutations, pleiotropy also occurs in perfectly normal genes, although researchers tend to use it to track and understand mutations in particular.

Genetic polymorphism Genetic polymorphism. Definition. noun. (1) The existence together of many forms of DNA sequences at a locus within the population. (2) A discontinuous genetic variation that results in different forms or types of individuals among the members of a single species.Supplement. Genetic polymorphism promotes diversity within a population.It often persists over many generations because no single form has an overall advantage or disadvantage over the others regarding natural selection. A common example is the different allelic forms that give rise to different blood types in humans.enetic polymorphism promotes diversity within a population. It often persists over many generations because no single form has an overall advantage or disadvantage over the others regarding natural selection.

- Polygenic inheritance occurs when traits are controlled by more than one gene. Since each person has about 25,000 genes, there are a huge number of possible gene combinations that could be related to a specific trait. It can be difficult to understand how these genes interact with one another.
