a
Sequence scanned for each region was mRNA: 1156 bp, non-MRNA: 4335 bp, 5′: 1059 bp, 3′: 846 bp, intron: 2430 bp, repeat: 1987 bp, and nonrepeat: 2348 bp, and total: 5491 bp.
b
S is the number of variable sites detected, excluding the indel at 5229A.
c
Average pairwise sequence difference; SE derived from stochastic and sampling variance, assuming no recombination (Tajima 1993).
