===Mixoploidy===
Mixoploidy is the case where two cell lines, one diploid and one polyploid, [[Chimera (genetics)|coexist within the same organism]]. Though polyploidy in humans is not viable, mixoploidy has been found in live adults and children.<ref>{{cite journal |title=Mixoploidy in humans: two surviving cases of diploid-tetraploid mixoploidy and comparison with diploid-triploid mixoploidy. |author=Edwards MJ |display-authors=etal |pmid=7810564 |doi=10.1002/ajmg.1320520314 |volume=52 |issue=3 |journal=Am J Med Genet |pages=324–330|year=1994 }}</ref> There are two types: diploid-triploid mixoploidy, in which some cells have 46 chromosomes and some have 69,<ref>{{cite journal |title=46,XX/69,XXX diploid-triploid mixoploidy with hypothyroidism and precocious puberty. |last1=Järvelä |first1=IE |last2=Salo |first2=MK |last3=Santavuori |first3=P |last4=Salonen |first4=RK |pmid=8301657 |volume=30 |issue=11 |pmc=1016611 |journal=J Med Genet |pages=966–967 |doi=10.1136/jmg.30.11.966|year=1993 }}</ref> and diploid-tetraploid mixoploidy, in which some cells have 46 and some have 92 chromosomes.
