Which of these is true about the type of parthenogenesis ?

Options

A. In arrhenotoky , only males are produced by parthenogenesis while in thelytoky only females are produced by parthenogenesis.
B. In arrhenotoky , only females are produced by parthenogenesis while in thelytoky only males are produced by parthenogenesis.
C. In arrhenotoky , only either males or females are produced by parthenogenesis while in thelytoky only females are produced by parthenogenesis.
D. In arrhenotoky , only males are produced by parthenogenesis while in thelytoky only either males or females are produced by parthenogenesis.

Answer

**Step-by-Step Solution:**

1. **Understanding Parthenogenesis**:
- Parthenogenesis is a form of asexual reproduction where an organism develops from an unfertilized egg. This means that fertilization is not required for reproduction.

2. **Types of Parthenogenesis**:
- There are two main types of parthenogenesis:
- **Arhenotauci**: In this type, only males are produced from unfertilized eggs.
- **Teletauci**: In this type, only females are produced from unfertilized eggs.

3. **Analyzing the Statements**:
- The first statement claims that in Arhenotauci, only males are produced, and in Teletauci, only females are produced. This statement is correct.
- The second statement suggests that RNO-talky (which seems to be a typographical error for Teletauci) produces only females. This is misleading as it does not specify the type correctly.
- The third statement claims that RNO-talky produces either male or female. This is incorrect because it does not align with the definitions of the types.
- The last statement suggests that RNO-talky produces only males, which contradicts the definition of Teletauci.

4. **Conclusion**:
- Based on the analysis, the first statement about Arhenotauci producing males and Teletauci producing females is the only correct statement regarding the types of parthenogenesis.

**Final Answer**: The correct statement is that in Arhenotauci, only males are produced by parthenogenesis, while in Teletauci, only females are produced.
