A single ortholog pair had a Ka/Ks ratio of approximately 1, signifying neutral selection (no selective pressure), while only one other pair showed gene divergence with a Ka/Ks ratio greater than 1.
But more importantly, this choice of terminology signifies the selection criteria used for Dutchness in the project, importing a specific, problematic, common sense notion of Dutchness as a form of identity into the reference database.
A large shape parameter results in a sharply peaked distribution of turnover rates and therefore signifies weak selection.
The elders placed blades of grass or stalks of wheat in Ahmad's turban to signify his selection.
These ω values are quite low and signify purifying selection.
The ratios ω > 0, ω = 0, and ω < 0 signify positive selection (adaptive molecular evolution), neutral mutations, and negative selection (purifying selection), respectively.
SSDs increased, becoming more positive (signifying weaker selection on big fish), as length deviation increased, mesh size decreased, and abundance of salmon increased.
Differences in gene assignments between H. melpomene and Z. filipendulae could signify different selection pressures on the genes in the two species, derive from the fact that many of the Heliconius ESTs originate from wing disc cDNA libraries, and not larvae as in Z. filipendulae, or, more likely, be artifacts resulting from a low number of GO-annotated genes in both species.
Fellow linebacker Ken Brown was named a first-team All-Big East selection, signifying his status as one of the best players at his position in the conference.
In recognition of his performance, he was named a first-team All-Big East selection, signifying his status as the best player at his position in the conference.
