When plasmogamy occurs between two fungi of compatible mating types, 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 thus can achieve higher rates of transcription and translation, and make more digestive enzymes per 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 bodies can be produced, increasing the number of spores produced during meiosis.
D)Karyogamy can occur more rapidly when a dikaryotic hypha encounters a compatible mating type.

Question

Quizplus · Accepted Answer

Dikaryotic hyphae can have multiple cells with different mating types, allowing for multiple potential sites of karyogamy and increased production of spores during meiosis.
