Figure 11.9 If a mutation occurs so that a
it still be able to reproduce?
To analyze:
Whether the fungus is able to reproduce, in case if a mutation takes place and the fungus is not able to produce a minus mating type.
Introduction:
Fungi are the eukaryotic species, which comprise both the multicellular and unicellular species in their genera. In fungi, reproduction is a complicated procedure and certain environmental factors play an essential function in the process of reproduction. Reproduction can take place both sexually and asexually on the basis of the existence and non-existence of the adequate environmental conditions.
Explanation of Solution
Mutation refers to the modification in the sequence of nucleotide that changes the genetic composition of the species. It can result in a harmful effect on the functioning individual and may even result in a fatality. In case, if mutation takes place in the fungus and it influences the generation of minus mating type, then the fungus would no longer possess the tendency to reproduce sexually.
However, the fungus would have the tendency to generate offspring with the help of asexual mode of reproduction. This process would incorporate the fungal hyphae to generate spores that upon meiosis will further produce fungal hyphae. The hyphae can also go through the process of fragmentation from which novel colonies can be developed. Apart from these, it can also reproduce asexually by budding.
The life processes of the fungus to reproduce sexually as well as asexually permits the fungus to reproduce, even in the non-existence of sexual reproduction conditions.
