Reducing the lifespan of flowers to one tenth of the baseline value, so that the average number of visits per flower is reduced from 20 to 2, leads to a further decrease in the divergence of corolla-tube depth (0.24±0.08 units).
GISH analysis of Nicotiana allopolyploids provided direct evidence for a decrease in the divergence between the parental genomes during the evolution via exchange and homogenisation of repeats [ 49].
Indeed, there is a noticeable decrease in the divergence for the 3'- COI region between S. latissima and the following Ectocarpales species: Leathesia difformis, Asperococcus bullosus, Punctaria latifolia, Elachista fucicola, Hincksia granulosa, Scytosiphon lomentaria, and Petalonia fascia.
Moreover, the SSL peak density will increase (decrease) in the convergence (divergence) vertical shear region of zonal wind.
Although some recent studies suggest that increasing concentrations of PFCs may decrease fecundity, divergence in the methodological approaches used to evaluate this association have prevented firm conclusions being reached.
In addition, a consistent decrease of divergence was observed in both comparisons of human-chimpanzee and two rice lines as the total number of exons or introns increased (Fig. 5E F).
Our study clearly demonstrates that there is no decrease in capture efficiency within 1.5% divergence (such is the level of T. striatus to T. alpinus).
If the effectiveness of selection on synonymous sites increases with Ne, then this predicts a decrease in the level of synonymous divergence relative to polymorphism, leading to overestimation of adaptive nonsynonymous evolution.
Both lines were then maintained with 20 sires at each generation, without any decrease in the abdominal fat content divergence, which remained close to a factor of three at generation 35.
It might be a consequence of diversifying selection that increased the structural divergence among genomes, and of purifying selection that decreased nucleotide divergence in each R gene locus.
