The first period the first phase
() of the cell is the G1,
by S and and then by
mitotic phase.

In the ploidy (the DNA
molecules in cell) can be
by the formula (n is the
of DNA molecules a gamete
cell a given species). S DNA
duplicates the quantity of
material increases from to 4n. In
that quantity is : 4n. After the
phase the quantity genetic
material decreases 2n in each
cell.
