Mitosis is used to produce genetically identical cells which diploid number of chromosomes.
Cells produced using mitosis have the same number of chromosomes as the parent cell.
Cells produced using mitosis have the same genes as the parent cell, which ensures that every cell in a multicellular organism has all the genes that it needs and that they are genetically identical.
Mitosis allows a successful genome to be inherited without changes by offspring in asexual reproduction.
Meiosis is used to halve the number of chromosomes form diploid to haploid.
Cells produced by meiosis have half as many chromosomes as the parent cell (diploid - haploid).
Pairs of genes in a diploid mother cells are dealt randomly to daughter cells, so there are almost limitless numbers of possible combinations, generating genetic diversity.
