You are studying two loci, A and B. Imagine that all assumptions of HWE are met in the population, except for selection. There is selection on locus A, but not on B. Under what conditions do you expect allele frequencies to change at locus B? a. It will change, but only when it is in LD with A b. It will change regardless of whether it is in LD with A or not c. It will change, but only when not in LD with A d. It will not change regardless of whether it is in LD with A or 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.
