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.

- The figure below shows the life cycle of the fungus Neurospora. The adult stage of the Neurospora is a multicellular haploid: a. Between which two stages of the Neurospora life cycle do most mitotic cell divisions occur? b. Neurospora has an arginine amino acid synthesis pathway shown below: Suppose I have a neurospora strain that has a mutation such that it will not grow unless I supplement the media (food) with arginine (but not with citrulline or ornithine). What gene is mutated? Explain your reasoning. c. Suppose I take the strain above that only grows with arginine supplements and cross it to a different mutant Neurospora strain that grows with arginine and citrulline supplements but not ornithine supplements. Assming genes A, B and C are unlinked and there is only one mutation per strain: i) What percentage of the progeny will grow on ornithine? ii) What percentage on citrulline? iii) What percentage on arginine?

- Most eukaryotic organisms use sexual reproduction as their primary means of perpetuating their species. Gametes are formed via meiosis. However, some species primarily reproduce via asexual means. Reproduction is accomplished via mitosis. Aspen trees most commonly reproduce by such asexual methods of cloning.What are the advantages and disadvantages of reproduction by asexual means?

- When the Ascomycetes fungus reproduces sexually, mating type A fungi cross fertilize mating type a fungi. The resulting zygotes undergo meiotic and then mitotic division to produce asci with eight ascospores. The ascospores in the asci are ordered and reflect the position of the parental nuclei in the zygote. Use the passage to answer the question.
