Question

In which type of Parthenogenesis are only males produced?

• A. Arrhenotoky
• B. Thelytoky
• C. Amphitoky
• D. Both (a) and (c)

Hint:

Remember: Arrhenotoky → Males, Thelytoky → Females.

Answer 1

The Correct Option is A

Concept: Parthenogenesis is a form of reproduction in which an organism develops from an unfertilized egg.
Step 1: Types of parthenogenesis.

• Arrhenotoky $\rightarrow$ Only males are produced (e.g., honeybees)
• Thelytoky $\rightarrow$ Only females are produced
• Amphitoky (Deuterotoky) $\rightarrow$ Both males and females are produced

Step 2: Evaluate options.

• Arrhenotoky $\rightarrow$ Produces males (correct)
• Thelytoky $\rightarrow$ Produces females (incorrect)
• Amphitoky $\rightarrow$ Produces both sexes (incorrect)
• Both (a) and (c) $\rightarrow$ Incorrect

Step 3: Conclusion.
Thus, arrhenotoky is the type of parthenogenesis that produces only males.
