Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Examples of human polygenic inheritance are height, skin color, eye color and weight.Polygenes exist in other organisms, as well. polygene, multiple factor, multiple gene inheritance, or quantitative gene is a group of non-epistatic genes that together influence a phenotypic trait. The precise loci or identities of the non-allelic genes are often unknown to biologists.
Sibling DNA testing, often referred to as a sibling paternity test, is a DNA comparison between two or more alleged bothers and sisters.

Our sibling DNA testing services stands above all others in pricing and exceptional quality and includes testing for two siblings.
