When Plasmogamy Occurs Between Two Fungi of Compatible Mating Types

question 2

Multiple Choice

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.
