Hint: A type of cell division that leads to two daughter cells each having an equivalent number and type of chromosomes because of the parent nucleus, typical of ordinary tissue growth. Mitosis is known to involve five phases, supporting the physical state of the chromosomes and spindle. These phases are prophase, prometaphase, metaphase, anaphase, and telophase.
Complete answer:
In the metaphase stage, all the chromosomes are arranged at the cell equator. All the chromosomes have two chromatids, joined at the centromere. These are called sister chromatids. The centromere splits in the anaphase stage and the two sister chromatids go to opposite poles. They are now called chromosomes. They have a single chromatid which will duplicate into two sister chromatids in the S phase. Thus, at the anaphase stage, the number of chromosomes remains the same even as the number of chromatids is reduced to one-half due to the splitting of the centromere.
Additional Information:
Stages in mitosis:
These phases are prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis is the final physical cell division that follows telophase and is therefore sometimes considered a sixth phase of mitosis.
So, the correct answer is, “The same number of chromosomes and half the number of chromatids”.

Note:
| Mitosis | Similarities | Meiosis |
| 4 Stages in total (plus interphase). | Production of new cells | 8 stages in total (plus interphase). |
| Happens in somatic cells | Similar basic steps | Happens in germ cells. |
| The purpose is cellular proliferation. | Start with a single parent cell. | The purpose is sexual reproduction. |
| Produces two diploid daughter cells. | Produces 4 haploid daughter cells. | |
| Chromosome number remains the same. | Chromosome numbers get halved in each daughter cell. | |
| Genetic variation doesn’t change. | Genetic variation seems to be increasing. |
