How to find how many genes control the additive trait

Polygenic Traits are Additive. Most traits are polygenic, meaning more than one gene contributes to their phenotypes. In this case, an individual inherits multiple copies of each allele, rather than inheriting one copy of each allele, from each parent. So, when a trait is polygenic, the alleles are additive. #PolygenicTraits #AdditiveTraits #genotype #phenotype #DNA #mRNA #Genetics
