Dikaryon biology definition
WebMedical Definition of dikaryon. 1 : a pair of associated but unfused haploid nuclei of a fungus cell capable of participating in repeated cell division as separate entities prior to their ultimate fusion. 2 : a cell having or a mycelium made up of cells each having a dikaryon — compare homokaryon. WebThe regularity of this process results in every cell of the dikaryon containing two sets of homologous chromosomes: that is, the dikaryon is a functional diploid. This is an important point. The so-called ‘higher organisms’ (plants and animals) are diploid but most true fungi are haploid, and this has genetic and evolutionary consequences.
