It karyokinesis is not followed by cytokinesis, then gives rise to

Options

A. Zygote
B. Fertilised egg
C. Multinucleate condition
D. Embryo

Answer

**Step-by-Step Text Solution:**

1. **Understanding Karyokinesis and Cytokinesis:**
- Karyokinesis refers to the division of the nucleus during cell division, while cytokinesis is the process that follows, which involves the division of the cytoplasm. Both processes are essential for the formation of two distinct daughter cells.

2. **What Happens if Cytokinesis Does Not Occur:**
- If karyokinesis occurs but is not followed by cytokinesis, the nucleus divides, but the cytoplasm remains undivided. This results in a single cell containing multiple nuclei.

3. **Resulting Condition:**
- The condition that arises from karyokinesis without cytokinesis is known as a multinucleate condition. This means that the cell has multiple nuclei within a single cytoplasmic mass.

4. **Evaluating the Options:**
- **Zygote:** Incorrect, as a zygote is formed from the fusion of male and female gametes, not from karyokinesis.
- **Fertilized Egg:** Incorrect, as it is synonymous with a zygote and does not relate to the process of karyokinesis and cytokinesis.
- **Multinucleate Condition:** Correct, as explained, this condition arises when karyokinesis occurs without cytokinesis.
- **Embryo:** Incorrect, as an embryo is a developmental stage that occurs after the zygote has undergone division.

5. **Conclusion:**
- The correct answer to the question is that if karyokinesis is not followed by cytokinesis, it gives rise to a multinucleate condition.
