Endomitosis is

Options

A. Mitosis without nucleus
B. Mitosis within nucleus
C. Frequent mitosis
D. Mitosis in uterine wall

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Endomitosis":**
- The term "endomitosis" can be broken down into two parts: "endo" meaning inside and "mitosis" referring to the process of cell division. Therefore, endomitosis refers to a type of mitosis that occurs inside the nucleus of a cell.

2. **Process of Endomitosis:**
- During endomitosis, the chromosomes within the nucleus undergo replication and division. This means that the chromosomes duplicate and separate, but the nucleus itself does not divide.

3. **Result of Endomitosis:**
- Since the nuclear division does not occur, the result of endomitosis is an increase in the number of chromosome sets within the nucleus, leading to a condition known as polyploidy. This means that there are multiple sets of chromosomes present in the nucleus.

4. **Characteristics of Endomitosis:**
- Endomitosis is characterized by:
- Mitosis occurring within the nucleus.
- Absence of nuclear division.
- Resulting in polyploidy, where the cell has multiple sets of chromosomes.

5. **Conclusion:**
- To summarize, endomitosis is defined as the process of mitosis occurring inside the nucleus without the division of the nucleus itself, leading to an increase in chromosome number and resulting in polyploidy.
