WebSNPs are now the primary source of genetic variation measured in mapping studies. Genetic markers need not be causative alleles and simply serve as a means of ascertaining allelic state at a genomic location. Once genotypes and phenotypes are collected, association of genotype with phenotype can be performed. WebNov 26, 2024 · In general, mutation is the primary source of genetic variation, which is the raw material for evolution through natural selection. A change in the DNA sequence is a mutation. Often these differences in gene sequences may be beneficial for an organism. By modifying genes and alleles in a population, mutations result in genetic variation.
