During fungal reproduction, which of the following processes is first to occur after the nuclei of opposite mating types fuse?

A. Spore reproduction

B. Gamete production

C. Mitosis

D. Meiosis

the answer is D: meiosis

During fungal reproduction, Meiosis is first to occur after the nuclei of opposite mating types fuse.

Explanation:

Meiosis a process that takes place in gametangia (a sex organ in fungus), in which gametes of different mating type are formed. At this stage the spores are being disseminated in the environment.

Meiosis performs dual function i. e reducing the genetic content as well as doubling the genetic diversity by recombination. After reproduction required a reduced DNA division mediated by the meiosis.
