A filament with normal configuration is left-handed with a helical pitch of about 2.2 μm, a helical diameter of about 0.4 μm, and 5340 flagellin subunits per turn.
The mean twist per strand is 18°, which is comparable with that of globular proteins (30±30°) [ 28, 29] and the overall β-sheet twist is left handed, consistent with reports that this is the most energetically favourable case [ 30].
If, in prehistory, this translated into increased reproductive success, it might have been enough to maintain a certain proportion of left-handers in the population, by balancing the costs of being left-handed with the advantages gained in fighting.

Those differences arise because, although 50% of offspring from two CC parents (CC × CC) would be left-handed in the single-locus case, with multiple loci, the C i alleles may be at different loci (e.g., D iC i; D jC j × D pC p; D qC q), producing only 25% of left-handedness.
