Sentence examples for mapping populations this from inspiring English sources

However in several other studies using different mapping populations this QTL has not been observed [ 40, 44, 45].

Despite a certain heterogeneity of recombination frequencies between mapping populations this must mainly be attributed to the dependency of estimated gene orders on sample size [ 31].

Putting the genetic distances of the two common markers together with the genes in the two different mapping populations, this study indicated that the two genes reside 11.2 cM apart.

Only 18 of the 253 polymorphic EST-microsatellite markers produced multiple (2-7) marker loci in the mapping populations; this indicated that the vast majority of the markers were highly conserved throughout the Iris genome, and are thus excellent resources for comparative mapping.

Using maximum-likelihood approach in two versions (De Givry et al. 2005): (a) if one assumes that the data from different sets represent a single map, i.e. same order and distances (this situation is referred to as genetic merging); or (b) if the same order is assumed, but recombination rates differ between the mapping populations (this situation is referred to as order merging).

Since only small numbers of recombination events can be accumulated over the few generations during the development of a recombinant inbred line mapping population, this approach has rarely led to candidate gene isolation [ 6].

Indeed, unlike the study in soybean by [ 20] phenological traits had no role in determining yield in the ICCV 2 × JG 11 mapping population, this might be due to the fact that both genotypes were early maturing and the range of variation in phenology was small.

With only two mapping populations for this phenotype, we saw improvements of 37% to 51%, in 1-LOD confidence intervals.

Thus, the ultimate genetic source of purple color in the three mapping populations in this study varied geographically and phenotypically.

No extra costs are required to develop and phenotype specific mapping populations and this approach enables screening a high number of individuals and alleles, increasing relevance for the breeding process.

The mapping populations in this study also segregate for similar traits and the SSR markers will therefore be useful to indicate the LG locations of the QTLs and the nearby SNPs will help to reveal and validate similar QTL regions for yield components and FAC in P2 and OxG, respectively.
