Metaphase I and anaphase I in a, b diploid (2n=2x=26) and c–f tetraploid (2n=4x=52) T. sinensis. Note a 13 II and b 13:13 distribution of chromosomes at anaphase I. Note quadrivalents, trivalents, bivalents and univalents in c (5IV+1III+10II+9I) d (10IV+5II+2I) and e, f 26:26 distribution of chromosomes at anaphase I. Scale bar: 10 µm.
