totaly both are different.meiosis is a reduction division.i mean the chromosome number reduces to half at the end.But in mitosis the chromosome remains the same.
My scientific studies have afforded me great gratification; and I am convinced that it will not be long before the whole world acknowledges the results of my work.-Gregor Mendel

really? So the S phase is different?

Cis or trans? That's what matters.

The difference is not on the S phase.
The differences are the meiosis is the reduction of chromosomes number compared parent cell.

In Meiosis Prophase I is different from Prophase in mitosis where there is crossing over occur.

In Metaphase I, the homologous chromosomes are aligned at the equatorial line while metaphase in mitosis not.

In Anaphase I, the homologous chromosomes are separated while sister chromatids are split at centromere in Anaphase of mitosis.
