A cell during anaphase. Microtubules are visible in green. Stages of late M phase in a vertebrate cell. Anaphase (from Ancient Greek ἀνα-() 'back, backward' and φάσις (phásis) 'appearance') is the stage of mitosis after the process of metaphase, when replicated chromosomes are split and the newly-copied chromosomes (daughter chromatids) are moved to opposite poles of the cell.
This results in the two daughter cells receiving an uneven chromatid. [4] Since the two resulting chromatids lack telomeres, when they replicate the BFB cycle will repeat, and will continue every subsequent cell division until those chromatids receive a telomere, usually from a different chromatid through the process of translocation .
Anaphase is a very short stage of the cell cycle and it occurs after the chromosomes align at the mitotic plate. Kinetochores emit anaphase-inhibition signals until their attachment to the mitotic spindle. Once the final chromosome is properly aligned and attached the final signal dissipates and triggers the abrupt shift to anaphase. [26]
The multiple centrosomes segregate to opposite ends of the cell and the spindles attach to the chromosomes haphazardly. When anaphase occurs in these cells, the chromosomes are separated abnormally and results in aneuploidy of both daughter cells. [2] This can lead to loss of cell viability [3] and chromosomal instability. [4]
When dicentric chromosomes form, a series of events can occur called a breakage-fusion-bridge cycle: Spindle fibers attach onto both centromeres in different locations on the chromosome, thereby tearing the chromatid into two pieces during anaphase. The result is a pair of DNAs with broken ends that can attach to other broken-ended DNA segments ...

Among these authors, the threshold for classifying automixis as a sexual process depends on when the products of anaphase I or of anaphase II are joined together. The criterion for "sexuality" varies from all cases of restitutional meiosis, [4] to those where the nuclei fuse or to only those where gametes are mature at the time of fusion. [3]
