Editing Ploidy (section)

===More than one nucleus per cell===
In the strictest sense, ploidy refers to the number of sets of chromosomes in a single [[nucleus (cell)|nucleus]] rather than in the cell as a whole. Because in most situations there is only one nucleus per cell, it is commonplace to speak of the ploidy of a cell, but in cases in which there is more than one nucleus per cell, more specific definitions are required when ploidy is discussed. Authors may at times report the total combined ploidy of all nuclei present within the cell membrane of a [[syncytium]],<ref name="D'Amato-2002">Encyclopedia of the Life Sciences (2002) "Polyploidy" Francesco D'Amato and Mauro Durante</ref> though usually the ploidy of each nucleus is described individually. For example, a fungal [[dikaryon]] with two separate haploid nuclei is distinguished from a diploid cell in which the chromosomes share a nucleus and can be shuffled together.<ref>{{cite web |url=http://www.utm.utoronto.ca/~anders38/ms.pdf |title=Dikaryons, diploids, and evolution |author1=James B.
