Genetic linkage maps of each chromosome are made by determining how frequently two markers are passed together from parent to child.
Linkage map
A genetic map assembled from recombination data that shows the order of mutant sites and genes along a nucleic acid molecule.
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 A map of a chromosome showing distances between loci in terms of the genetic recombination distances between them. See genetic map ...
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.

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

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.
Deletion mapping -- the use of overlapping deletions to localize the position of an unknown gene on a chromosome or linkage map.
Mapping See gene mapping, linkage map, physical map.
Marker An identifiable physical location on a chromosome (e.g., restriction enzyme cutting site, gene) whose inheritance can be monitored.
A unit for distance in a linkage map. The distance equal to 1% recombination between two loci.

The distance between two linked gene pairs where 1 percent of the products of meiosis are recombinant. A unit of distance in a linkage map. The distance equal to 1% recombination between two loci.

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, ...
