Variation in mt transcription profiles among representatives of ten families from the S. vulgaris population Kovary Meadows. Total RNA was transferred to the membrane and hybridized with DIG labeled atp1 probe (A) or cox1 probe (B). H - hermaphrodite; F - female; F* - individuals possessing mt DNA haplotype different from siblings show also different transcription patterns which correspond to the specific mt haplotypes. Family codes are written below each Northern. Ribosomal RNAs corresponding to the specific RNA samples are visualized below the panels. The numbers on the side indicate RNA molecular size (nt).
