Heterokaryon
A heterokaryon is a
cell that contains multiple, genetically different
nuclei. A cell with two separate nuclei formed by the experimental fusion of two genetically different cells. (A medical example is a heterokaryon composed of nuclei from Hurler syndrome and Hunter syndrome. Both of these diseases result in problems in mucopolysaccharide metabolism however a heterokaryon of nuclei from both of these diseases exhibits normal mucopolysaccharide metabolism proving that the two syndromes affect different proteins and so can correct each other in the heterokaryon).

Heterokaryon
A cell with two separate nuclei formed by the experimental fusion of two genetically different cells. (Heterokaryons, for example, composed of nuclei from Hurler syndrome and Hunter syndrome, both diseases of mucopolysaccharide metabolism, have normal mucopolysaccharide metabolism proving that the two syndromes affect different proteins and so can correct each other in the heterokaryon).
Heterokaryon
A cell containing more than one genetically different nuclei. Naturally occurs in fungi as long as their fungal (heterokaryon) incompatibility types are identical (see also dikaryotic).
