  2. Genetic distance - Wikipedia

    en.wikipedia.org/wiki/Genetic_distance

    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 ]

  3. Centimorgan - Wikipedia

    en.wikipedia.org/wiki/Centimorgan

    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 ...

  4. Genetic linkage - Wikipedia

    en.wikipedia.org/wiki/Genetic_linkage

    Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction.Two genetic markers that are physically near to each other are unlikely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be more linked than markers that are far apart.

  5. Gene mapping - Wikipedia

    en.wikipedia.org/wiki/Gene_mapping

    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.

  6. Human evolutionary genetics - Wikipedia

    en.wikipedia.org/wiki/Human_evolutionary_genetics

    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.

  7. Physical mapping - Wikipedia

    en.wikipedia.org/wiki/Physical_mapping

    Physical map is a technique used in molecular biology to find the order and physical distance between DNA base pairs by DNA markers. [1] It is one of the gene mapping techniques which can determine the sequence of DNA base pairs with high accuracy. Genetic mapping, another approach of gene mapping, can provide markers needed for the physical ...

  8. Genetic recombination - Wikipedia

    en.wikipedia.org/wiki/Genetic_recombination

    In genetic engineering, recombination can also refer to artificial and deliberate recombination of disparate pieces of DNA, often from different organisms, creating what is called recombinant DNA. A prime example of such a use of genetic recombination is gene targeting , which can be used to add, delete or otherwise change an organism's genes.

  9. Genetic map function - Wikipedia

    en.wikipedia.org/wiki/Genetic_map_function

    Where d is the distance in map units, the Morgan Mapping Function states that the recombination frequency r can be expressed as =.This assumes that one crossover occurs, at most, in an interval between two loci, and that the probability of the occurrence of this crossover is proportional to the map length of the interval.
