However, as observed with Scenarios 4 and 5, independence between paternal and maternal gametic effects, together with the presence of a significant paternally inherited variance component can also be due to the existence of a strong and negative genetic correlation between direct and maternal genetic effects.
But some mtDNA sequences didn't fit neatly into a tree of maternal descent (Science, 5 March, p. 1435), so Philip Awadalla of the University of Edinburgh and Adam Eyre-Walker Eyre-Walker and John Maynard Smithersity of Sussex in Brighthe decided to look for signs of mixing between paternal and maternal mtDNA.
Conflict between paternal and maternal resources during pregnancy is thought, at least in some cases, to drive imprinting of genes [13].
Moreover, a high degree of consanguinity (47% first cousin marriages[9]) and local endogamy, generate a situation in which each paternal household in a specific geographic region is a subpopulation isolate in which there is a strong correlation between paternal and maternal household identity[10].
However, the relationships between paternal and maternal PCMDS in couples remain unclear.
The possible interaction effect between paternal and maternal alcohol use was also tested.
Genome length estimates differed between paternal and maternal data sets (Table 3).
> -wrap-foot> Including the difference between paternal and maternal age resulted in very similar results for all the models presented.
However, we conducted a sensitivity analysis by including the difference between paternal and maternal age as a covariate.
Overall, our results indicate that polymorphic CmCGG methylation does not have a strong effect on gene expression in the reciprocal F1 triploids, and that the changes in gene regulation between paternal and maternal-excess triploids are not controlled by CmCGG methylation.
Although children as characters are present only in the background (with one brief exception), the book is preoccupied with the parent-child relationship: with having or not having children, with choosing between paternal-maternal and romantic-sexual love, or working out what to tell children when they ask what life is for.
