As a result of this incompatibility we are losing approximately a lane's worth of capacity in addition to those closed by the roadworks themselves.
Indeed, Serrano et al. [ 40] reported that at the latest stage of olive flower development, once the stigma was completely brown, papillae cells exhibit PCD symptoms as a result of the incompatibility reaction between pollen and papillae stigma cells.
Although most hybrids are disadvantaged as a result of genetic incompatibility, the surviving offspring may have a beneficial combination of their parental genotypes, allowing them to adapt to changing environments.
The GT1 and GT5 lines did not deviate from expected Mendelian segregation, indicating homeologous recombination of the transgene locus on an A-genome chromosome (the A genome is shared by the two parental taxa, B napus AACC- and B. rapa AA genomes), and hence the transgene would have a decreased chance of being lost in subsequent backcrossing as a result of genomic incompatibility.
The phenotypic flower alterations observed could have their origin in genomic instabilities, as a result of putative incompatibilities between nuclear genes, or between nuclear and cytoplasmic (mitochondrial) genes.
It has been suggested that hares with an alien mtDNA have a lowered fitness as a result of a functional incompatibility between the cytoplasmatic mitochondrial genes and the cell nucleus [ 10].
Thus, we postulate that the rapid evolution of mobile DNA across macropodid marsupial species may result in an incompatibility within species hybrids that is manifest in the male germline as a result of expressed piRNA incompatibilities [ 2, 14, 41].
Moreover, being localized on the nuclear genomes, ITS2 and 18S rRNA genes can become divergent paralogous copies as a result of incomplete concerted evolution and sexual incompatibility among individuals [ 68, 69].
Genetic incompatibilities as a result of outbreeding may lead to variance in mating speed and other pre-copulatory traits.
