Thirdly, the transition between amino acids is favored by one-codon mutation, especially the last codon in the codon triplet.
Therefore, strains that incorporate a second factor in their CI mechanism would be favored by selection relative to one-factor strains, as the latter could never rescue the first but vice versa.
At that point, escalating the arms race will no longer be favored by natural selection, and the evolutionary one-upping will stop.
Breaking large inversions into smaller ones might be favored by natural selection if these chromosome segments contained or were tightly linked to loci involved in reproductive isolation, as it has been suggested that multiple shorter inversions might have a stronger effect in suppressing recombination than one large inversion [28], [29].

They say that tests of the devices in New York last winter showed steep declines in ratings for series on UPN that are favored by black viewers, like "One on One" and "The Parkers".
A compensatory mutation that re-sets a normal pairing is favored by the selection, replacing one Watson--Crick pairing for another or for slightly less stable guanine and uracile pairs [ 38].
