How is meiosis related to genes?

MeiOSis allows a cell to form into 4 cells (by meiOSis 1 (which is literally mitosis) and meiOSis 2 (mitosis without DNA replication))

in meiOSis 1, the cells exchanges DNA information between homologous pairs, this allows genes to be transferred and creates 4 unique and distinct cells.

segragation of alleles occur too.
