When plasmogamy occurs in two compatible mating types of fungi, a dikaryotic cell is formed in the hyphae. For some groups of fungi, only one or a few cells are dikaryotic
In other groups of fungi, a majority of the cells that make up the fungal hyphae are dikaryotic. What might be an advantage of having dikaryotic hyphae? A. Dikaryotic hyphae have more nuclei and there can be higher rates of transcription and translation and more digestive enzymes made by each cell. B. Dikaryotic hyphae are able to divide more rapidly than hyphae with only one nucleus. C. Karyogamy can occur in more than one cell and more fruiting bodes can be produced, increasing the number of spores produced through sexual recombination. D. Karyogamy can occur more rapidly when a dikaryotic hypha finds an alternate mating type.
