Sentence examples for positions and effect from inspiring English sources

For a given number of QTL and heritability level, QTL positions and effect sizes were generated randomly for each simulation run (see next section).

The chromosomal positions and effects of putative QTLs were determined by composite interval mapping in QTL Cartographer 2.0 software (Basten et al. 2002).

The QTL positions and effects were randomly generated anew for each data set.

The estimates for positions and effects of QTL detected by all methods are fairly close to true parameter values.

The results from simulation studies indicate that the positions and effects of multiallelic QTLs can well be estimated with a modest sample and heritability.

In an RJMCMC process (Appendix B), the number of SNP associated with QTL, their positions and effects were sampled, conditional on the estimated variance components of,, and.

On the other hand, disequilibrium between genes on a QTL and another QTL makes their positions and effects more difficult to estimate accurately [ 24, 25, 35].

However, since the true QTL positions and effects are unknown in empirical studies, these studies could not independently validate the superiority of joint-family analyses.

Zhang et al. [ 5] demonstrated that segregation distortion may not necessarily increase number of false QTLs or significantly affect the estimation of QTL positions and effects.

All the estimates of QTS positions and effects were quite robust for different heritabilities, but the epistatic interaction effects with environments between SNP.44 on the second chromosome and SNP.63 on the third chromosome deviated a little from the true value.

Thus, it is necessary to investigate the impacts of selection upon linkage analyses in order to obtain unbiased estimates of QTL position and effect.
