WebSep 13, 2012 · Non-additive genetic variation is usually ignored when genome-wide markers are used to study the genetic architecture and genomic prediction of complex traits in human, wild life, model … Additive genetic effects occur when two or more genes source a single contribution to the final phenotype, or when alleles of a single gene (in heterozygotes) combine so that their combined effects equal the sum of their individual effects. Non-additive genetic effects involve dominance (of alleles at a single locus) or epistasis (of alleles at different loci).
WebJun 18, 2024 · Non-additive and ethnic-specific genetic effects have been largely ignored in GWAS for complex traits of human, animals, and plants . However, several recently published GWAS of human and plant complex traits revealed the importance of non-additive genetic effects and their large contributions to phenotypic variations [28,42]. … WebJun 15, 2024 · This study showed that the additive effects provide the large part or all of G × S for growth, ecophysiological, and tree form traits, as well as wood chemical properties, except Klason lignin. The additive and non-additive genetic effects can be effectively better exploited with the availability of genome-wide markers.
WebGenetic Variance. Since the genetic variance comprises additive, dominance, and epistatic variances, the proportion of phenotypic variance accounted for by total genetic variance is defined as heritability in broad sense, while that accounted for by additive and additive × additive epistasis variance only is defined as heritability in narrow sense. WebNov 12, 2024 · For example, eye color is encoded by 16 individual genes, all with additive genetic effects. However, there are clearly more than 16 shades of eye color that exist in the human population.
WebFeb 19, 2024 · For example, the rs109922122 located at 55,191,677 bp on chromosome19 had a P-value of 2.01E-5 for additive genetic effect, but only had a P-value of 0.003 for dominance effect.
