Which one of these statements concerning polygenic and multifactorial traits is NOT true? they can either be continuous or discontinuous a smooth gaussian distribution can occur through environmental influences a smooth gaussian distribution can occur through increasing numbers of genes polygenic traits require the additive effect of many genes; multifactorial traits do not
Genetic Variation
Genetic variation refers to the variation in the genome sequences between individual organisms of a species. Individual differences or population differences can both be referred to as genetic variations. It is primarily caused by mutation, but other factors such as genetic drift and sexual reproduction also play a major role.
Quantitative Genetics
Quantitative genetics is the part of genetics that deals with the continuous trait, where the expression of various genes influences the phenotypes. Thus genes are expressed together to produce a trait with continuous variability. This is unlike the classical traits or qualitative traits, where each trait is controlled by the expression of a single or very few genes to produce a discontinuous variation.
