Factors that contribute to genetic variation
WebIt seems logical that natural selection would work toward genetic uniformity; the genotypes that are most fit produce the most offspring, increasing the frequency of adaptive alleles and eliminating less adaptive alleles. Yet there remains a great deal of genetic variation within populations. Describe factors that contribute to this variation. WebApr 6, 2024 · Even today, researchers are still discovering new types of variants within human genomes. Human genomic variation is particularly important because a very small set of these variants are linked to …

In natural selection, organisms with environmentally … WebHere, we describe evolutionary rates for 11,492 ortholog pairs between Arabidopsis thaliana and A. lyrata and investigate possible contributors to rate variation among these genes. Rates of evolution at synonymous sites vary along chromosomes, suggesting that mutation rates vary on genomic scales, perhaps as a function of recombination rate.
