How are meiosis I and meiosis II different?
At the end of meiosis I, both of the resulting daughter cells are haploid (definitely not diploid). However, the chromosomes are still double-stranded. The homologous pairs have already been separated. In humans, this means that the original cell had 23 pairs of chromosomes, and the cells at the end of meiosis I have 23 chromosomes (not pairs), each of which still have two sister chromatids. At the end of meiosis II, there are a total of four daughter cells, each of which is diploid. At this point, the sister chromatids have separated from each other. In humans, this means that these gametes each have 23 chromosomes, each of which has one chromatid.
