Which of these meiosis stages is functionally the most similar to mitosis? stages of meiotic division typical in the formation of spermatozoa. meiosis i meiosis ii meiosis i with ii neither meiosis i nor ii?

Meiosis II is a simpler and shorter process than meiosis I and the cells that enter meiosis II are made from meiosis I. Thus, these cells are haploid which means they just have one chromosomes from each homologous pair but these chromosomes still have two sister chromatids.
