By finding recombination frequencies for many gene pairs, we can make linkage maps that show the order and relative distances of the genes on the chromosome.
24 gru 2022 · Map distance tells the expected number of crossovers between two loci and can be used as a proxy of recombination; the longer the map distance the higher the recombination frequency.
A genetic map shows the map distance, in cM, that separates any two loci, and the position of these loci relative to all other mapped loci. The genetic map distance is roughly proportional to the physical distance, i.e., the amount of DNA between two loci.
A genetic linkage map describes the position of a species' or experimental population's known genes or genetic markers in terms of recombination frequency rather than a particular physical distance along each chromosome.
A measure of the genetic differences between two populations or closely related species is called genetic distance, and it is often calculated using allele frequency data from several loci in each of the two populations.
29 maj 2020 · We review three approaches to infer recombination rate variation from genetic variation derived from high-throughput sequencing data: population-based, pedigree-based and gamete-based.
23 sty 2015 · We propose new distance measures for estimating genetic distances between individuals when allelic variation, gene dosage and recombination could compromise standard approaches.
