Web10 apr. 2024 · Quantitative trait locus (QTL) analysis and genome-wide association studies (GWAS) are widely used approaches in the analysis of complex traits, and are commonly used to explore the genetics of both human diseases and phenotypes in model organisms. However, these methods commonly rely on univariate or interval mapping approaches … WebN2 - The role of epistatic effects in the determination of complex traits is often underlined but its significance in the prediction of pigmentation phenotypes has not been evaluated so far. The prediction of pigmentation from genetic data can be useful in forensic science to describe the physical appearance of an unknown offender, victim, or missing person who …
WebTwo or more genes may produce similar and cumulative effects on the same trait. In humans, the skin colour difference between so-called blacks and so-called whites is due to several (probably four or more) interacting pairs of genes, each of which increases or decreases the skin pigmentation by a relatively small amount. Epistatic genes.
