Distribution of cytoplasmic haplotypes among populations of Lobelia siphilitica varying in sex ratio

Distribution of plastid and 3-locus mitochondrial haplotypes among 220 individuals of Lobelia siphilitica. Individual samples are identified by their population of origin, population location (US state or Canadian province), and the sex of the plant (female, F or hermaphrodite, H). Average population sex ratio (percent female averaged across years) and sex-ratio quartile (0%, 0.1-10%, 10.1-50%, >50% female) are also shown. Plastid haplotypes are based on intergenic sequences of psbK–rps16, excluding an imperfect minisatellite locus (13 unique haplogroups labeled 'C#'). Concatenated 3-locus mitochondrial haplotypes are based on sequenced alleles of nad7ab (A–K), atp6 (1–11) and Ψrps12 (a–f). '_' indicates missing sequences for a particular mitochondrial allele. Mitotype classes: C= common mitotypes found in at least 5 individuals and at least 3 populations; RA= rare mitotypes with rare alleles for at least one marker locus; RR= rare combinations of common alleles at each marker locus.
