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.

AFLP loci that were heterozygous in both parents could help bridge homologous linkage groups of the co-parental map.
The marker number per linkage group ranged from 4 (group 22) to 36 (group 1) with a mean of 8.
For this characteristic, at the most superficial depth (5 to 25 cm,), one QTL was detected, as well as in the distal fraction of the linkage group associated with chromosome 3, positioned at 256-260 cM, between the markers OsC1r3_18199829 and OsC1r3_18195592 with LOD = 3.
When compared with the accuracies on the single linkage group model, the accuracies of GEBV for the MLM were lower than those in the SLM.
AFLP markers in a molecular linkage map of maize: codominant scoring and linkage group distribution.
The number of markers actually scored per linkage group was much greater than the number of independent markers in our unrestricted, neutral simulations of introgression.
At Boardman, linkage group E was found to carry two different QTLs each for height and basal area, whereas there was no common linkage group for these two traits at Clatskanie.
This map was based on 183 molecular markers, including SSR, ISSR and RAPD markers, mapped onto 16 linkage groups (12 larger and six smaller).
For each trait, the number of OTL detected in each linkage group, the LOD value of the OTL and the average of the results obtained were calculated from the analyses of all 100 simulations.

Consistent with this alignment, genetic mapping of the human CHS locus in affected families localized it to 1q42-1q44 as part of a conserved linkage group shared with mouse chromosome 13 (80,81).
