Which of the following is true at the end of the mitotic cell division process regarding chromosome number?

Options

A. Chromosome number in a daughter cell is less than that in the parent cell.
B. Chromosome number in a daughter cell is less than or equal to that in the parent cell.
C. Chromosome number in a daughter cell is equal to that in the parent cell.
D. Chromosome number in a daughter cell is greater than or equal to that in the parent cell.

Answer

To determine which statement is true regarding chromosome number at the end of the mitotic cell division process, we can analyze the options provided. Here’s a step-by-step solution:

### Step 1: Understand the Process of 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 essential to recognize that mitosis maintains the chromosome number.

**Hint:** Mitosis results in two identical daughter cells.

### Step 2: Evaluate the First Option
The first option states that the chromosome number in the daughter cell is less than in the parent cell. This is incorrect because mitosis does not reduce the chromosome number; it maintains it.

**Hint:** Think about what happens to chromosome numbers during mitosis.

### Step 3: Evaluate the Second Option
The second option claims that the chromosome number in a daughter cell is less than or equal to that in the parent cell. This is also incorrect, as mitosis ensures that the chromosome number remains the same, not less.

**Hint:** Remember that mitosis produces identical cells.

### Step 4: Evaluate the Third Option
The third option states that the chromosome number in a daughter cell is equal to that in the parent cell. This is correct because mitosis results in two daughter cells that are genetically identical to the parent cell, including having the same chromosome number.

**Hint:** Identify the key feature of mitosis regarding chromosome numbers.

### Step 5: Evaluate the Fourth Option
The fourth option suggests that the chromosome number in a daughter cell is greater than or equal to that in the parent cell. This is incorrect because mitosis does not increase the chromosome number.

**Hint:** Consider how chromosome numbers are conserved during cell division.

### Conclusion
The correct statement at the end of the mitotic cell division process regarding chromosome number is that the chromosome number in a daughter cell is equal to that in the parent cell.

**Final Answer:** The chromosome number in a daughter cell is equal to that in the parent cell.
