The correct Answer is:
To solve the question "A hybrid where the cytoplasm of two parent cells are fused by retaining only one parental nucleus is called," we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Terminology**: - The question is asking about a specific type of hybrid formed by the fusion of cytoplasm from two parent cells while retaining only one parental nucleus. 2. **Identify the Key Features**: - The hybrid must have: - Cytoplasm from two different parent cells. - Only one nucleus from one of the parent cells. 3. **Analyze the Options**: - **Option A: Asymmetric Somatic Hybrid**: This type of hybrid retains the full somatic complement of only one parent, which does not fit our criteria. - **Option B: Cybrid**: This term refers to a hybrid that has cytoplasm from two parent cells but retains only one nucleus. This matches our description. - **Option C: Interbreed**: This typically refers to the breeding between two different species to produce offspring, which does not fit the criteria. - **Option D: Symmetric Somatic Hybrid**: This type retains the full somatic complement of both parental species, which again does not match our criteria. 4. **Select the Correct Answer**: - Based on the analysis, the correct answer is **Option B: Cybrid**. ### Final Answer: A hybrid where the cytoplasm of two parent cells are fused by retaining only one parental nucleus is called **Cybrid**. ---
