    In meiosis one, after division do the we still have 46 chromosomes in each cell? Because they said it copies before it divides so do we have 46?

    I think at the end you meant to say that the sperm and egg fuse to make a haploid cell- since they combine their 23 chromosomes to make 46, they wouldn't be diploid any more.

    • @rossatron1818
      @rossatron1818 5 месяцев назад +3

      when they fuse i think they are creating a new normal body cell so it would be diploid not haploid
