Further, no significant bias away from first codon positions, in terms of the distribution of polymorphic sites, could be detected.
Many of the singleton polymorphic sites reported here will have been selected by chance and do not necessarily represent polymorphisms with high frequencies.
All enzymes cut at polymorphic sites; in total 18 haplotypes were found, with approximately five haplotypes per population (table 3).
These polymorphic sites presumably appeared due to transposition and were accumulated during the maintenance of sublines.
Only 11 polymorphic sites are present in a sample of 20 chromosomes and these sites present a significant excess of rare-frequency variants.
Although only 2 human isolates were compared, we provide evidence for a high number of polymorphic sites.
This test allows an overall assessment of the recombination within a group of sequences based on a pairwise examination of the silent polymorphic sites.
All polymorphic sites were double-checked manually.
Polymorphic sites accounted for 3.09 % of these sites and 2.38 % of sites were informative.
The test is similar to a # test comparing the observed and expected values for the number of polymorphic sites within each of two species and the between-species divergence.
By reducing the size of the region and considering only the polymorphic sites that occur at relatively high frequency, we generated a data set that is amenable to statistical analysis.
If many mutations are unique, these will contribution more to estimates based on polymorphic sites, and they will have less impact on the average pairwise difference in the sample.
