Additive genetic effects - Wikipedia
WEBAdditive genetic effects occur where expression of more than one gene contributes to phenotype (or where alleles of a heterozygous gene both contribute), and the phenotypic expression of these gene (s) can be said to be the sum of these contributions.
Additive genes Definition and Examples - Biology Online
WEBAdditive genes are those genes that code for the same trait and their effects work together on the phenotype. An example of a function of additive genes is on the eye colour. Several genes work together to determine the colour of the eye of an offspring.
Additive Genetic Effects - an overview | ScienceDirect Topics
WEBAdditive genetic effects occur when alleles (alternative forms of a gene) at a locus (place on a chromosome) and across loci add up to affect a trait. From: Advances in Child Development and Behavior, 2013

WEBAdditive genetic effects refer to the contribution of alleles at multiple genetic loci that act additively to influence a trait, without any interactions between alleles within or between loci.

WEBAug 29, 2017 · An example frequently cited for additive genetic effects in humans is pigmentation. A variety of genes and gene loci determine how much pigment is produced by nonalbino individuals and the contribution of each allele of these loci is additive which means the more functional alleles one has, the darker the pigmentation.

WEBA simple additive model of inheritance was adequate to explain the genetic basis of most agronomic traits including seedcotton yield, lint yield, boll weight, number of bolls plant −1, lint percent, and lint and seed indices under well-watered conditions, but dominance effects were larger than additive effects under water-limited conditions ...
