Genetic information is copied and
passed on to daughter cells
G1, S, G2= Interphase
S= Synthesis, DNA is copied 2n- 4n
M= Mitosis followed by cytokinesis
What happens in synthesis
Diploid organisms copy their DNA during synthesis phase. Chromosomes viewed during mitosis have

Comparing meiosis to mitosis
Meiosis produces sex cells from the cells in the sex organs. There are two divisions where prophase,
metaphase, anaphase and telophase occur twice.
The chromosomes are copied (as in a mitotic cell cycle)
4n-----2n -----n HAPLOID
Meiosis produces 4 haploid cells, they are genetically different.
Meiosis introduces variation in a species.
Mitosis results in genetically identical cells being produced.…read more
