Sexual reproduction in yeasts is by:
Correct answer: A. Ascospores
- A. Ascospores
- B. Basidiospores
- C. Conidia
- D. Both a and b
Explanation
The correct answer is ascospores. In yeasts, sexual reproduction typically involves the formation of ascospores, which are produced in a sac-like structure called an ascus, characteristic of the Ascomycota phylum to which yeasts belong. Basidiospores are associated with Basidiomycota fungi, such as mushrooms, and are not involved in yeast reproduction. Conidia are asexual spores, not involved in sexual reproduction, making option c incorrect. Option d is incorrect because it suggests both ascospores and basidiospores are involved, which is not the case for yeast sexual reproduction.
