Expert Solution & Answer

Summary Introduction

To analyze:

If a fungus can still reproduce in case the fungus undergoes mutation and is unable to produce a minus mating type.

Introduction:

Fungi can reproduce both sexually and asexually. Sexual reproduction can occur by fusion of two gametes that can be similar in size (isogamous), or dissimilar (anisogamous). Asexual reproduction occurs by fragmentation or asexual spore formation such as zoospores.

Explanation of Solution

Yes, a fungus that is unable to produce minus mating type will be able to reproduce. Reproduction in the fungus can also occur asexually by fragmentation of its hyphae to produce a daughter fungus or asexual spores.

Conclusion

The fungus that is unable to multiply sexually can still reproduce asexually by spore formation and fragmentation.
