linkage group

   Also found in: Dictionary/thesaurus, Medical, Wikipedia 0.01 sec.

linkage group

All the genes on a single chromosome. They are inherited as a group; during cell division they act and move as a unit rather than independently. Variations in linkage groups can occur if a chromosome breaks, and the sections join with the partner chromosome if it has broken in the same places. This exchange of genes between chromosomes, called crossing-over, usually occurs during meiosis. Sex linkage is the tendency of a characteristic to be linked to one sex; sex-linked traits in humans include red-green colour blindness and hemophilia.

linkage group [′liŋ·kij ‚grüp]
(genetics)
The set of gene loci that show significantly less than 50% recombination with one or more other genes within the set; given enough mapped genes, it corresponds to one complete chromosome of the complement. The genes located on a single chromosome.

It will be interesting to see if the pair of loci (Med 362 and Med 722) that showed some evidence of linkage (significant deviation from linkage equilibrium), when mapped, will be close together in the same linkage group.

Genetic linkage mapping based on a population of nearly 500 Doubled Haploid Lines was able to position three or four members of this gene family on linkage groups 17, 24, and 28, respectively (two of the four observed polymorphic restriction fragments containing alpha-tubulin genes are either identical or map too close to each other on linkage group 17 to be distinguishable in map distance).
