potato is considered to be an autopolyploid and, as such, exhibits
Genomic in situ hybridization (GISH) reveals both autopolyploid and allopolyploid origins of different North and Central American hexaploid potato (Solanum section Petota) species.
However, this study, which suggests speciation associated with autopolyploid changes in chromosome number, is based on mitotic counts, which are notoriously difficult to interpret in Carex except in species with the lowest numbers.
