The current interest in discovering the molecular basis of complex diseases uses either linkage or candidate gene approaches.
The performance of this new approach was also evaluated using the leave-one-out procedure under a test scenario of either simulated linkage analysis and whole-genome scan.
In both rhizobium strain treatments, there were QTL that influenced multiple traits, indicative of either tight linkage between loci or pleiotropy, including one QTL with opposing effects on growth and reproduction.
It will facilitate the genetic dissection of important quantitative traits either by linkage mapping as we reported in this paper, or by genome-wide association mapping.
At some chromosomal regions, QTL controlling more than one growth-related traits were detected, suggesting either the linkage of two or more QTL (one for each trait), or the presences of a single QTL on each LG with pleiotropic effects.
In such cases, measurements of linkage either cannot be made or become highly inaccurate when extrapolated over the time between sample points.
E2s are capable of mediating linkage specificity, either on their own, by the use of a cofactor or with the help of the respective substrate 6, 7.
The EST- microsatellite loci were not evenly distributed in either of the linkage maps.
Further study will be required to define conditions that may allow resolution of these additional linkage isomers either.
Twelve DArTs were removed during the course of map construction either because of lack of linkage to other markers, or as they formed small linkage groups containing only DArTs which did not link to the known chromosomes.
