Figure 7.2 (a) In animals, sexually reproducing adults form haploid gametes from diploid germ cells. (b) Fungi, such as black bread mold (Rhizopus nigricans), have haploid-dominant life cycles. (c) Plants have a life cycle that alternates between a multicellular haploid organism and a multicellular diploid organism.

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