This comparison defined 181 conserved linkage groups
, approximately 90% of the mouse genome.
This similarity may be caused by linkage between Odh and Est; they may both mark the same linkage group
and thereby jointly mark the phenotypic variation.
In the female linkage map, 16 linkage groups
with an average number of 7.3 loci per linkage group
were found and mapped (Table 2).
The phenomenon of linkage group
conservation appears to be a common feature in the evolution of other eukaryotic groups.
Shrimp Map: a low-density, microsatellite-based linkage map of the Pacific whiteleg shrimp, Litopenaeus vannamei: identification of sex linked markers in linkage group
The terminal-most or near terminal-most genetic marker loci on each of the 17 linkage groups
were genotyped in addition to genetic marker loci spaced as evenly as possible throughout each of the 17 original linkage groups
However, we reported information indicating that microsatellites TUMXLv10.208 and TUMXLv10.220, homologs of 28s rRNA gene, located on to the same linkage group
where Sex locus was located on
For each of the 31 linkage groups
, the highest LOD scores generated in each permutation run were then ranked, and the 50th and 10th highest values from each distribution represented the 5% and 1% group-wise threshold LOD scores.
The TRAP H64.245, forming a partial linkage group
consisting of three TRAP markers, was linked with QTL conditioning resistance to common bacterial blight expressed in greenhouse leaf inoculation assays (19 and 30% of phenotypic variation explained, [R.sup.2]) (Table 3).
All crossovers for each line and linkage group
were then simply summed and standardized by putting this sum in the numerator of a fraction with the potential crossovers (number of markers per chromosome--1) in the denominator.
Three clusters were found: two being located on linkage group
2 in male map and one on linkage group
6 in female map.
