what is the relationship between genes and traits expressed in individuals? a) gene code for DNA, which is primarily responsible for individual traits b) Gene code for proteins, which are primarily responsible for individual traits c) genes code for chromosomes, which are primarily responsible for individual traits d) gene codes for carbohydrates, which are primarily responsible for individual traits
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.
