The table below shows four human populations (CLM, MXL, PEL, PUR). A single nucleotide polymorphism with alleles A and G has been genotyped in each of these populations. For each genotype, the frequency is shown, and the number of individuals with that genotype in the sample is in brackets. What is the frequency of the A allele in the CLM population? 0.80 0.76 0.88 0.84
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.
