Anaphase 1 - homologous chromosomes separate

Anaphase 2 - sister chromatids separate, but the cell is haploid

Anaphase of mitosis - sister chromatids separate, but the cell is diploid

Microtubules are polymers of tubulin protein which elongate and shorten during cell cycle and cause the movement of chromosomes.

13. All sons are colour blind
