Sentence examples for been under selective pressure from inspiring English sources

We show that five beta-defensin genes that do not show copy number variation in humans show evidence of positive selection in catarrhine primates, and identify specific codons that have been under selective pressure.

Several genes involved in determining skin color have been under selective pressure in Europeans and East Asians.

This independence suggests that a small patch of chromosomal region around the HWC2 locus might have been under selective pressure.

Because these loci are unlikely to have been under selective pressure, variants altering drug metabolism have in some cases increased to reasonable frequency and can be associated with large effects [14].

These results indicate that most of these human and mouse regulatory regions have been under selective pressure both at the sequence and functional level.

To check whether the loci are neutral or targeted by natural selection, the distribution of FST against the probability to be under selective pressure was simulated with BayeScan software [ 32].
