Which of the following is not a function of mitotic cell division in animals?

Options

A. Growth and repair
B. CeII replacement
C. Asexual reproduction
D. Gametes formation

Answer

To determine which of the following is not a function of mitotic cell division in animals, we need to first understand the primary functions of mitosis.

### Step-by-Step Solution:

1. **Understand Mitosis**: Mitosis is a type of cell division that results in two daughter cells, each having the same number of chromosomes as the parent cell. It is crucial for growth, repair, and asexual reproduction in multicellular organisms.

2. **Identify Functions of Mitosis**:
- **Growth**: Mitosis allows organisms to grow by increasing the number of cells.
- **Repair**: It helps in repairing damaged tissues by replacing dead or damaged cells.
- **Asexual Reproduction**: In some organisms, mitosis is responsible for asexual reproduction, producing genetically identical offspring.

3. **Contrast with Meiosis**: Meiosis, on the other hand, is a type of cell division that reduces the chromosome number by half and is essential for the formation of gametes (sperm and eggs). This is a reductional division, which is not a function of mitosis.

4. **Conclusion**: Since mitosis does not involve the formation of gametes, the function that is not associated with mitotic cell division in animals is gamete formation.

### Final Answer:
The function that is not a function of mitotic cell division in animals is **gamete formation**.
