Differences in additives to cigarettes commonly smoked by African Americans could also explain the observed racial differences in cotinine.
There was no significant difference in additive or logistic EuroSCORES between the groups.
However, when estimated from the difference in additive genetic variance estimated between models that included the GRM, the amount of variance explained decreased to only 24 30% of the total additive genetic variance being explained by the selected SNPs.
Thus, for Extraversion, there are qualitative sex differences in the additive and non-additive genetic effects, but the additive and non-additive genetic effects are of equal magnitude in males and females: 24 % and 25%%, respectively.
The differences in non-additive gene expression between our study and previously reported estimates can potentially be attributed to technological capacities of short- and long-oligonucleotide microarray platforms and differences between genotypes used to create allopolyploids.
The resulting d/a distribution is very similar to the d/a distribution generated by all DE genes, indicating that platform feature biases are not causing the differences in non-additive profiles observed between the microarray platforms.
In addition to a low genetic correlation between PB and CB performance, the degradation of accuracy might result from differences in non-additive effects.
Even at loci with differences in methylation between parents, the hybrids often exhibit additive inheritance (i.e., no trans effect) with each allele retaining the methylation level exhibited in the parents.
When SNP effects must be estimated, the advantage of fitting BSAM over the additive GS model was not always observed under additive inheritance [ 9], which suggests that differences in LD between breeds may not be as important as the presence of dominant gene action in practice.
These authors parameterized the additional variability arising due to differences in allelic frequencies between breeds in terms of the interbreed additive variance [ 7], a parameter equivalent to twice the segregation variance as defined by Lo et al. [ 1].
