Nuclear-cytoplasm incompatibility results in abnormal growth phenotypes in higher plants [ 1, 2].
Custom-designed flight chambers (modified from Benzer, 1973) were used to test whether the mito-nuclear incompatibility results in performance defects.
In these studies, incompatibility resulting from the allopatric divergence between two genomes is considered as a predominant factor causing hybrid depression.
In addition, changing a response in two consecutive trials, or the presence of S-R incompatibility, resulted in the slowing of responses among the 6 to 9 years old children.
Another argument against the role of intrinsic genetic incompatibility resulting from a random process in the evolution of reproductive isolation can be found in comparing the estimations of lifetime of species, and of the time it takes for such incompatibilities to develop.
In the transgenic strains, uncoupled respiration was reduced in (simw ); Aatm Ore compared to (simw ); Aatm Aut, supporting the main effect of the tRNA-synthetase interaction, and suggesting that the mito-nuclear incompatibility results in decreased OXPHOS and O2 consumption, potentially contributing to some of the locomotor phenotypes characterized.
The predictions indicate that hot spot formation occurs when temperatures become unbounded in localized regions at the peripheries of RDX crystals where RDX estane interfacial incompatibilities result in crystal sliding and localized plastic deformation at RDX crystal edges and interfaces.
Physical incompatibilities result in visible (precipitate, color change, gas production) and invisible (subvisible particles, variations in pH) reactions.
The Bateson-Dobzhansky-Muller model posits that hybrid incompatibilities result from genetic changes that accumulate during population divergence.
Eucalypts are preferentially outcrossing with late-acting post-zygotic self-incompatibility resulting in outcrossing rates that can exceed 90%1, high levels of nucleotide variation23,24 and accumulation of genetic load and expression of inbreeding depression4.
