Evidence of autopolyploidy and translocations in the karyotype of Tigridia pavonia (Iridaceae, Iridoideae) from the Reserva Ecológica del Pedregal de San Ángel, Mexico Autoren: Tapia-Pastrana, Fernando, Tapia-Aguirre, Fernando

“… The haploid karyotype 6m + 8sm is proposed here.Conclusions: Cytogenetically, the presence of four satellites discards an allotetraploid origin and the evidence of possible translocations correlates with fragments, B chromosomes and fragile centromeres observed in other species of this genus. This supports the active role of translocations in the conformation of bimodal karyotype of T. pavonia. …”
