Karyograms of M. stelleri: (a) cytotype I, 2n = 44; (b) cytotype II, 2n = 43; (c) cytotype III, 2n = 42; (d) cytotype IV, 2n = 41; (e) cytotype V, 2n = 40 (according to Moreva and Borisenko 2017); NF = 44+2. The letter designations are as follows: m, metacentric; sm, submetacentric; sm-st, submeta-subtelocentric; st, subtelocentric; a, acrocentric chromosomes; the non-homologous subtelocentric chromosomes are boxed; the marker chromosomes are underlined once; the chromosomes similar in size to the marker metacentrics and submetacentrics are underlined twice. Scale bar: 10 μm.
