Sentence examples for been episodes of selection from inspiring English sources

SWAPSC analysis suggests that in both primate and rodent lineages there have been episodes of selection in historically consecutive branches that have affected the same regions of these genes.

Sites within the active, mature peptides have been subject to repeated episodes of selection in different primate lineages, and by implication are important in functional diversity.

And this is selection that occurred in just the last 25,000 to 5,000 years, because the signal from older episodes of selection is muffled by constant mutation in the DNA sequence.

Interestingly, we saw no evidence for this trade-off in the EE2 tanks, where selection differentials for premating sexual selection as well as for both postmating episodes of selection were all positive, favoring larger females (Table  1), but these results also must be interpreted with caution as the 95% confidence intervals for the selection differentials for postmating episodes overlapped zero.

The rationale is that since selective pressures could have changed over time for some biological pathways, recent or old episodes of selection cannot be detected by only looking at current human diversity.

A small number of sites in the mature human peptides were found to have undergone repeated episodes of selection in different primate lineages.

Therefore the additional sites detected by MEME and not by FUBAR are likely to have been subject to episodes of positive selection.

For example in the primate lineage there was an episode of positive selection ~40 92 MYA (branch E in Figure 1) which was followed by an episode of negative selection within the past ~14.5 million years (MY), with both episodes affecting positions 109 117 in the alignment.

Similar instances of elevated LD, mostly associated with past episodes of selection during the evolution of cultivated sunflower, are also visible elsewhere in the genome [ 29].

The total opportunity for selection in males was significantly lower than that in females, and the decomposition in males reveals different contributions of the various episodes of selection.

Much less frequently they are subject to episodes of positive selection, which are typified by accelerated sequence divergence and corresponding functional shifts [ 1- 6].
