Final answer:
No information is provided on the sexual reproduction of Gayralia oxysperma. Fungi with a mutation that prevents the production of a minus mating type can still reproduce asexually through the mitotic division of spores.
Step-by-step explanation:
The question regarding the sexual reproduction of Gayralia oxysperma is not addressed in the provided materials. Therefore, the answer to whether there is information on the sexual reproduction of Gayralia oxysperma is b) No. However, there is information on sexual and asexual reproduction in related contexts, such as in Oedogonium (a filamentous green algae), other green algae like Chlamydomonas, and various plant groups that exhibit alternation of generations (including bryophytes and ferns).
Regarding fungi, if a mutation occurs that prevents production of a minus mating type, the fungus will still be able to reproduce. The correct answer to this is c) Yes, it will be able to reproduce asexually by the mitotic divisions of spores. This highlights that fungi have more than one mode of reproduction and can continue to reproduce even when one reproductive strategy is compromised.
