Karyotype organisation of individuals of T. mirus from three populations (localities of each population are indicated in column 1).

The parental origins of the chromosomes were determined by GISH. Chromosome nomenclature of homeologous groups (A–F) followed Ownbey and McCollum [25] and Pires et al. [24]. Superscript letters indicate the genome origins of the chromosomes, du = T. dubius, po = T. porrifolius. Chromosomes carrying translocations are indicated by naming the chromosome according to the genomic origins of the centromeres, followed by the genome origins of the translocated segments. E-indicates chromosome set as expected from the diploid parents.
