Table 1. Diversity, divergence and summary statistics for the standard ZAL2 and inverted ZAL2m chromosomes in the white-throated sparrow.
| Region | Loci | Length (bp) | Segregating sites, S | π (All) | π (ZAL2) | π (ZAL2m) | FSTa | dxyb | Tajima's Dc | Tajima's D (ZAL2) | Tajima's D (ZAL2m) |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Inside inversion | 58 | 34 823 (13 789.3) | 277 (167) | 0.00293 (0.00449) | 0.00044 (0.00075) | 0.00030 (0.00042) | 0.94 | 0.00583 (0.00871) | 0.65 | −0.74 | −0.84 |
| Outside inversion | 4 | 1655 (777) | 17 (14) | 0.00191 (0.00296) | 0.00160 (0.00311) | 0.00238 (0.00455) | 0.21 | 0.00190 (0.00296) | −0.82 | −0.90 | −0.22 |
Numbers in parentheses are calculations for neutral sites, noncoding, synonymous sites outside most conserved elements.
a
FST is calculated by comparing all ZAL2 chromosomes with all ZAL2m chromosomes.
b
Divergence (dxy) between the ZAL2 and ZAL2m chromosomes is calculated as the average number of nucleotide substitutions per site.
c
Tajima's D values were calculated using four tan-stripe (TS) and four white-stripe (WS) birds, thus representing the natural population frequency of the ZAL2 and ZAL2m chromosomes.
