Abnormal chromosome behavior in the synthetic autotetraploid B. rapa. Normal chromosomal behavior displayed in the diploid B. rapa from early prophase to anaphase II (A–D), and normal chromosome morphology through early prophase and metaphase I was also observed in autotetraploids (E–G). However, a subset of cells consisting of multivalents and univalents (arrows) chaotically dispersed at metaphase I (H). Homologous chromosomes segregate equally during anaphase I forming two polar groups of chromosomes (I). Unequal segregation of chromosomes in the ratio of 19: 21 at anaphase I (J), Normal alignment of chromosomes in cell at metaphase II (K), but cells at anaphases II consist of unequally segregated chromosomes (L). Dotted oval consist of 19 chromosomes while solid oval has 21 chromosomes. Bar = 10 μm.
