@ Firstly start from Mitosis @
1) In mitosis DNA has been replicated but chromosome not visible.
2) Each duplicated chromosome have two identical sister chromosome are thicken
3) The chromosome Assemble at the centre means metaphase plate
4) The end of complete set of daughter found In each of pole
5) They are sexual
6) They occur In humans, plants
7) They discover by Oscar hartwig
@ Second meiosis @
1) Each chromosome is replicated and two identical sister called chromatids
2) They are asexual
3) They occur in all organism
4) They consist of two sister chromatids which come as pair.
5) They arranged as pair
6) they align of metaphase plate means (side)
7) they discover by Walter Fleming
8) they have cellular reproduction
Hope this helps :)
