The life cycle of fungi has many different patterns based on the species of the fungi. In higher fungi karyogamy is often delayed so that the hyphae remain dikaryotic.

Are chemoheterotrophs require organic compounds for both carbon and energy sources and fungi lack chlorophyll and are therefore not autotrophic. Terrestrial orchids produce protocorms that may remain belowground for several years before they emerge and produce their first leaves. Fungi with no known sexual reproduction molds.

How fungi are different from plants and actually are a lot more like animals this includes you.

However this fitness reduction is lower compared to a hypothetical life cycle where dikaryons can also exchange nuclei.
