This plot emphasizes that pair preferences are highest when the figure and ground have the same hue (but differ in saturation and/or lightness levels) and decrease monotonically as hue difference between the figure and ground increases.
Pair preferences were slightly, but significantly, correlated with the differences in coolness, such that pairs with warmer figures on cooler grounds were preferred to the reverse (r = +.13, p <.001).
Our measurements suggest that the best single relational variable in predicting pair preferences is perceived pair harmony, because average pair harmony ratings appear in all of the best-fitting regression models of average pair preference, accounting for 62% of the variance.
The large differences between the RSCU and RDCU tree topologies and branch lengths imply that codon preference and codon pair preference are shaped by different molecular mechanisms.
To analyze whether single codon preference or codon pair preference is more conserved on the evolutionary scale, we compared different bacteria according to RSCU (relative synonymous codon usage) and RDCU (relative dicodon usage).
It was claimed previously that codon pair preference is primarily determined by a tetranucleotide combination including the last nucleotide of the P-site codon and all three nucleotides of the A-site codon [ 16].
Thus, it appears that virtually all of the residual effects in these figural color preferences, after variations due to single and pair preferences have been removed, can be attributed to some form of contrast, all of which generally enhance preference for the figural color.
Also of possible interest is the "S" shaped reaction of the 2f-3aas occuR2snce R2s to higher GC content, that these R2s rise earlier in the coding-vs.-non-genic case, that 6fold R2showow a similar but much weaker reaction, and that the horizontally paired patterns of occurrences and preferences are often qualitatively similar.
Alternatively, whether preferences are expressed during short pair-wise encounters may depend on the mating status of the female (unpaired vs. paired).
Mating preferences are an important aspect of the pairing process.
