The two evolutionarily significant benefits of meiosis that are not present in mitosis are reshuffling of chromosomes and the crossing over.

What is the uniqueness of meiosis ?

Meiosis is the specific system with the aid of using which haploid (n) germ cells are produced with the aid of using successive cell divisions with out an intervening spherical of DNA replication

Crossing over takes place at some point of prophase I of meiosis earlier than tetrads are aligned alongside the equator in metaphase by meiosis II, most effective sister chromatids stay and homologous chromosomes were moved to split cells. Recall that the factor of crossing over is to boom genetic diversity.
Before the determine cell divides, a system acknowledged as 'recombination' takes place, which permits chromosomes in a couple to alternate bits of genetic information. This reshuffling guarantees that every chromosome in a cell is specific.
