A type of recombination, found in certain heterokaryotic fungi, that is based on mitosis rather than meiosis. Genetically distinct haploid nuclei fuse in the heterokaryon. The resulting diploid nuclei multiply by mitotic division, with some crossing over, and a diploid homokaryon develops from a diploid conidium. Chromosomes may be shed by the diploid nucleus to produce a haploid nucleus.
