This contrasts with results reported by Sulpice et al. (2009) on Arabidopsis showing a negative linkage between starch storage and biomass production, similar to our findings Luquet et al. (in press) and as observed on Cluster 1.
In addition, we are testing these RILs in multiple locations to obtain yield data, and to assess the effects of random-mating on breaking the negative linkage between yield and fiber quality traits.
Poon and Chao [ 21] demonstrated that recombination has a greater effect on fitness when genetic drift is larger, presumably since here negative linkage disequilibrium between beneficial mutations is greater, and thus sex serves to more effectively concentrate adaptive alleles.
However, due to the multiplicative nature of fitness across different sites, the inbreeding depression rate in the early generations immediately after the reduction in population size is expected to be smaller (larger) than B when there is positive (negative) linkage disequilibrium between deleterious alleles at the base population.
Statistical analysis revealed that an almost linear negative linkage was observed between EGFR mRNA expression levels and FVC, DLCO and 6(d)).
The shared condition for such situations is negative linkage disequilibrium (LD; <0) between fitness loci, as a result of weak negative epistasis, spatially and temporally varying selection (biotic or abiotic), or genetic drift [ 14, 15, 18– 20].
Rebolledo et al. (2012) reported a negative constitutive linkage between organ size and number, both contributing to early vigour.
The recently designed rice genomic SNP arrays (Yu et al. 2014; Chen et al. 2014) have offered molecular breeders excellent tools for the genetic background selection which could significantly reduce the recurrent cycles of backcrossing and help to break the negative genetic linkage between a target gene and poor agronomy trait.
Breeding efforts are under way to break the negative genetic linkage between dry matter and β-carotene content in this crop (http://www.harvestplus.org/sweetpotato3.html).org/sweetpotato3.html
Probabilistic linkage between the 45 and Up Study, the CCR and the APDC was done by the Centre for Health Record Linkage, 30 as described previously, resulting in approximately 0.1% false-positive and <0.1% false-negative linkages.
