Mitosis is not the only distributor of mutated cells: non-mitotic endopolyploid cells produce reproductive genome-reduced cells.

Abstract excerpt

Giant endopolyploid nuclei (>16n) can spontaneously fragment by endomitosis (nuclear internal division) into near-diploid cells with reproductive capacity (depolyploidization), and endotetra/octopolyploidy can undergo chromosome-visible meiotic-like genome reductional divisions also to replicative subcells. These unconventional divisions are associated with production of aneuploidy, which led to the question in...
