From: An adaptable chromosome preparation methodology for use in invertebrate research organisms
The optimized chromosome preparation protocol allows karyotyping of multiple planarian species. The optimized chromosome preparation protocol was used to generate karyotypes for two additional planarian species. a D. japonica. b, c Karyotypes obtained for D. japonica demonstrating the presence of both diploid (b) and triploid (c) cells in the same individual. d Table summarizing the ratio of diploid to triploid dividing cells in four D. japonica individuals. e P. velata. f, g A representative P. velata karyotype (f) and quantification of the number of chromosomes per cell (g)
