¹Significant Tajima’s D values shown in bold

²Average pairwise distance between U and V linked alleles; number of indels is shown in parentheses

³Average pairswise distance between C. purpureus and T. cylindricus, with number of indels in parentheses; missing values indicate poor outgroup sequence quality or outgroup nested within ingroup
