Figure 4

Metaphase cell and corresponding karyotype arranged from Giemsa-stained chromosomes of (a) sterlet Acipenser ruthenus (2n = 120), (b) Siberian sturgeon A. baerii (2n ~ 245), (c) hybrid of A. baerii (2n ~ 245), x spontaneous hexaploid A. baerii (2n ~ 368) resulting in (2n ~ 300) and (d) spontaneous hexaploid A. baerii (2n ~ 368); asterisks denotes „acipenserine“ cytotaxonomic marker, i. e. the group of the largest acrocentric chromosomes. Bars equal 10 μm.
