linkage map
A genetic map based on the frequencies of recombination between markers during crossing over of homologous chromosomes. The greater the frequency of recombination between two genetic markers, the farther apart they are assumed to be.

Linkage map. See Genetic linkage map.
Linked genes/markers. Genes and/or markers that are so closely associated on the chromosome that they are coinherited in 80% or more of cases.

Linkage map: A map of the relative positions of genetic loci on a chromosome, determined on the basis of how often the loci are inherited together. Distance is measured in centimorgans (cM).

gene linkage map: a map that pinpoints the location of genes based on their connection to certain marker gene sequences.
gene pool: the collection of genes within a population; as changes in the gene pool occur, a population evolves.

Genetic linkage map. A linear map of the relative positions of genes along a chromosome. Distances are established by linkage analysis, which determines the frequency at which two gene loci become separated during chromosomal recombination.

If two markers are genetically linked, they are on the same genetic map, also called a linkage map. The set of all markers on the same linkage map is called a linkage group.

The observation that some genes do not segregate independently at meiosis, broke the laws of Mendelian inheritance, and provided science with a way to map characteristics to a location on the chromosomes. Linkage maps are still used today, ...
