Relationships among mt DNA haplotypes derived from coding and flanking regions of the cox1 and atp1 genes and transcription profiles of these genes as revealed in S. vulgaris population from Kovary Meadows. Black circles denote transcription profiles possessing a strong additional band of the size about 2.1 kb. The cox1 PCR-RFLP haplotypes are designated KovA' and KovB', the atp1 PCR-RFLP haplotypes are designated KovA, KovB, KovC. The cox1 Southern RFLP variants are designated c41, c42, c44, c52, and c54. The atp1 Southern RFLP variants are designated a41, a42, a44, a52, a45, and a54.
