Solution
The correct option is C Rhizopus
The term heterothallism was first used by Blakeslee in 1904 for the condition of sexual reproduction, which he found in certain species of Mucorales (Zygomycota), such that conjugation is possible only through the interaction of two differing thalli. Two main types of heterothallism are- 1. Morphological heterothallism- e.g., Dictyuchns monosporus, Achlya bisexualis. 2. Physiological heterothallism- E.g., Mucor mucedo, Ascobolus magnificus, Sclerotinia Gladioli, Neurospora sitophila, Puccinia graminis. Thus the correct answer is option C.
