Genetic map
A map of gene positions on a chromosome. Distances between two genes can be determined by recombination and by genome sequencing project.

Genetic Map
A genetic map is a type of chromosome map that shows the relative locations of genes and other important features.
What is the relationship between the genetic map and the physical map of a chromosome? As a very rough rule of thumb, we shall assume that 1 cM on a chromosome encompasses 1 megabase (1 Mb = 106 bp) of DNA.
Genetic Mapping
Eric Lander reported the mapping of more than 1000 microsatellites toward a 2- to 3-year target of 6000 at the Whitehead-Massachusetts Institute of Technology (MIT) genome center.
genetic maps Diagrams showing the order of and distance between genes; constructed using crossover information.
genetics The study of the structure and function of genes and the transmission of genes from parents to offspring.
Genetic map
The relative position and distance between genes determined from recombination frequencies.
Genetic marker
A locus that has a useful phenotype which can be used for genetic selections or screens.
genetic map
An ordered list of genetic loci (genes or other genetic markers) along a chromosome.

Genetic map A map showing the distances between markers in terms of the frequency of genetic recombination between them.
[edit] Genetic maps
Genetic maps are very important to understand the structure and organization of genomes from which evolution patterns and syntenic relationships between species can be deduced.

Linkage map
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).
In genetic mapping studies an offspring having a non-parental allele combination. An individual or cell with a genotype produced by recombination.
Also known as: non-parental

One of the things that has come out of this genetic map is that now you have a fairly actuate placement of these variable regions, these markers, that allow you much more accurately to map genes and diseases, and what's more, ...
Furthermore, these SNPs can be extremely useful in genetic mapping (see 'Genetic Mapping') to follow inheritance of specific segments of DNA in a lineage.
