Population Genetics: Genetic distance can help in studying population genetics, understanding intra and inter-population genetic diversity. Taxonomy and Species Delimitation : Determining genetic distance through DNA barcoding is an effective tool for delimiting species especially identifying cryptic species . [ 15 ]
In genetics, a centimorgan (abbreviated cM) or map unit (m.u.) is a unit for measuring genetic linkage. It is defined as the distance between chromosome positions (also termed loci or markers) for which the expected average number of intervening chromosomal crossovers in a single generation is 0.01. It is often used to infer distance along a ...
There are two distinctive mapping approaches used in the field of genome mapping: genetic maps (also known as linkage maps) [7] and physical maps. [3] While both maps are a collection of genetic markers and gene loci, [8] genetic maps' distances are based on the genetic linkage information, while physical maps use actual physical distances usually measured in number of base pairs.
The genetic history of Europe includes information around the formation, ethnogenesis, and other DNA-specific information about populations indigenous, or living in Europe. European early modern human (EEMH) lineages between 40 and 26 ka ( Aurignacian ) were still part of a large Western Eurasian "meta-population", related to Central and ...
A graphical representation of the typical human karyotype The human mitochondrial DNA. 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.
Distance on a phylogenetic tree can be used approximately to indicate: Genetic distance. The genetic difference between humans and chimpanzees is less than 2%, [4] or three times larger than the variation among modern humans (estimated at 0.6%). [5] Temporal remoteness of the most recent common ancestor.

The bottom chart measures the genetic distance between all pairs of populations according to the Fst statistic. Populations separated by greater distance are more dissimilar than those that are geographically close. Isolation by distance (IBD) is a term used to refer to the accrual of local genetic variation under geographically limited ...
