After mitosis, the chromosome number of a daughter cell is the parent cell's

Options

A. doubled compared to
B. one-half
C. the same as
D. rerranged compared to

Answer

To solve the question regarding the chromosome number of daughter cells after mitosis, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two daughter cells that are genetically identical to the parent cell. This process is crucial for growth, development, and tissue repair in multicellular organisms.

2. **Chromosome Number**: The parent cell has a specific chromosome number, which is referred to as diploid (2n) in somatic cells. This means that it contains two sets of chromosomes, one from each parent.

3. **Equational Division**: Mitosis is described as an equational division. This means that the chromosome number remains the same before and after the division. The DNA content is duplicated during the S phase of the cell cycle, but during mitosis, the duplicated chromosomes are evenly distributed to the two daughter cells.

4. **Daughter Cells**: After mitosis, each daughter cell receives an identical set of chromosomes. Therefore, if the parent cell was diploid (2n), each daughter cell will also be diploid (2n).

5. **Conclusion**: Since the chromosome number in the daughter cells is the same as that in the parent cell, the correct answer to the question is that after mitosis, the chromosome number of a daughter cell is the same as the parent cell's.

### Final Answer:
The chromosome number of a daughter cell after mitosis is the same as the parent cell's (Option C).
