The Spectrum of Genetic Variation in Human Populations Variant allele frequency is a key factor to consider in the analysis of genome variation. We identified 29,983 polymorphisms within analyzed UCEs, but revealed that a vast majority exhibits very low minor allele frequencies.

Genetic variation was profiled using the Affymetrix Genome-Wide Human SNP Array 6.0. Human genetic variation is the genetic differences in and among populations.There may be multiple variants of any given gene in the human population (), a situation called polymorphism.No two humans are genetically identical. Large-scale studies of human genetic variation have focused largely on understanding the pattern and nature of single-nucleotide differences within the human genome. Variation in the human genome can take several forms. See our Privacy Policy and User Agreement for details.

Genetic variation or polymorphism - the regular and simultaneous occurrence in a single interbreeding population of two or more discontinuous genotypes. Results: We found that 109 genes were differentially expressed between left and right atrial tissues. Thus, one can view the fractal dimension as the result of reducing the dimensionality of the genetic variation as much as possible, while maintaining characteristics of genetic variation.

The genome analysis showed that rhesus macaques have more genetic variants per individual than humans. These regions of low genetic variation are referred to as being highly constrained and the team believes that they could indicate genes involved in the pathogenesis of developmental disorders.
