linkage map

link·age map

an abstract mathematical representation of genetic loci that conserves order of loci, which are spaced in such a way that the distances are algebraically additive; conventionally, a map is scaled so that as distances between loci become smaller the ratio of the map distance to the value of the recombination fraction approaches 1 and independently assorting loci are infinitely far apart.

Studies have shown that the homologous regions of wheat, rice, Brachypodium, and sorghum genomes are powerful tool for constructing genetic linkage maps. The powdery mildew resistant genes, Pm36, Pm41, Pm51, andMlIW170, and the stripe rust resistant gene Yr26 were identified by comparative genomics analysis, and linkage markers were also designed using the collinear regions in wheat, rice, Brachypodium, and sorghum (ZHANG et al.
