What are the main differences between meiosis 1 and meiosis 2?
There are few differences.
First, in prophase 1(meiosis 1) chromatin condenses to form chromosomes which are paired to give homologous pairs. While prophase 2(meiosis 2) does not have any pairing.
Secondly, in anaphase 1(meiosis 1), the pair breaks and one chromosome each moves to the opposite side of the pole. While anaphase 2(meiosis 2) has chromosomes broken into sister chromatids that move to opposite poles.
Thirdly, in meiosis 1 a diploid cell gives two haploid cells. while in meiosis 2 two haploid cells divide to give four haploid cells.
