In some species parthenogenesis may alternate with sexual reproduction this process is called

Options

A. Complete parthenogenesis
B. Incomplete or cyclic parthenogenesis
C. Both the above
D. None of the above

Explanation

To solve the question regarding the process in which parthenogenesis alternates with sexual reproduction, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- Parthenogenesis is a form of asexual reproduction where an organism develops from an unfertilized egg.
- Sexual reproduction involves the fusion of male and female gametes.

2. **Identify the Context**:
- The question mentions that in some species, parthenogenesis alternates with sexual reproduction. This means that these species can reproduce both sexually and asexually in different generations.

3. **Explore the Options**:
- The options provided are:
- A) Complete parthenogenesis
- B) Incomplete and cyclic parthenogenesis
- C) Both of the above
- D) None of the above

4. **Analyze the Options**:
- **Complete Parthenogenesis**: Refers to a scenario where reproduction occurs solely through parthenogenesis without any sexual phase.
- **Incomplete and Cyclic Parthenogenesis**: Refers to a life cycle where both parthenogenetic and sexual phases occur alternately. This is often seen in certain insect species.

5. **Select the Correct Answer**:
- Since the question specifies that parthenogenesis alternates with sexual reproduction, the correct term that describes this phenomenon is **Incomplete and Cyclic Parthenogenesis**.

6. **Final Answer**:
- Therefore, the answer to the question is **B) Incomplete and cyclic parthenogenesis**.
