Does metaphase of mitosis meiosis 1 or meiosis 2 have the haploid number of chromosomes at the equator of the spindle?
Metaphase of meiosis 2 has the haploid number of chromosomes at the equator of the spindle. In meiosis 1, during metaphase, there are still pairs of homologous chromosomes lined up at the equator.
What happens in meiosis 1 that doesn't happen in meiosis 2?
DNA is copied
How do meiosis 1 differ from those of meiosis 2?
Anaphase of Meiosis 1 separates the homologous chromosome pairs, but during Anaphase of Meiosis 2, the sister chromatids are separated instead. Also, Meiosis 1 starts with one diploid cell and ends with 2 haploid cells, whereas Meiosis 2 starts with the 2 haploid cells and ends with 4 haploid cells (gametes).
At what stage do cells starting mitosis and meiosis begin with a?
