Which one of the following shows heterothallism?
A
Rhizopus
B
Bacterium
C
Cycas
D
Ricinus
Correct Answer
Option A
Detailed Explanation
Heterothallism refers to a reproductive strategy in which two genetically distinct mating types are required for sexual reproduction, commonly observed in fungi. Rhizopus, a genus of zygomycete fungi, exhibits heterothallism as it requires the fusion of different mating types (e.g., + and - strains) to form zygospores, distinguishing it from the other options, which do not display this reproductive mechanism.
