The KL divergence reduces towards the bottom right corner, which indicates convergence.
However, hybrids may be less competitive in secondary stages of naturalization, as increased population divergence reduces hybrid fitness [ 113].
When plotting nucleotide divergence against Ka/Ks ratio, a significant negative relationship was found (R = −0.61; P = 0.01), suggesting that the nucleotide divergence reduces as the pressure of positive selection increases.
We repeated the analysis removing positions with the highest score values, until θ λ I was not significantly different from 0. Using this strongly conservative criterion, the firm candidates to be involved in the functional divergence reduce to two (63 and 73) and one (23) positions, in the previous comparisons.
Furthermore, in this case there exists an analytical solution for modified Jensen-Rényi divergence, which reduces the computational burden of the algorithm and improves the accuracy of the solution.
Once such demonstrations are made, it will be necessary to test whether, and how, expression divergence actually reduces gene flow between natural populations.
The modifications also improve the method's power to detect random variation in divergence times, reducing the tendency to estimate clustered divergences.
We postulate this mixed breeding system permits such rapid postglacial divergence of D. parvula and D. retrocurva, with selection against migrants (immigrant inviability) maintaining this divergence by reducing the homogenizing effects of dispersal.
Side-mode suppression ratio ∼20 dB is obtained for proposed devices from threshold to rollover currents at all measure temperatures, with the peak output power of ∼30 mW at 10 K in pulsed mode and lateral divergence angle reduced by half.
Including this one, ten studies have scanned the human genome for regions of selective sweeps to date, with varying levels of success by utilizing extended linkage disequilibrium, elevated divergence and reduced homozygosity [4], [9], [17] [23].
Because a very high divergence can reduce the power for the detection of positive selection under models of variable ω ratios among sites [79], we excluded the sequence of fish and rodents, leaving other sequences in the dataset.
