Mitosis produces two daughter cells that are genetically identical to the parent cell and to each other, and cytokinesis divides the cell so there are two separate cells of similar size and composition.

Relevant knowledge points and concepts:
- Mitosis is the nuclear division process in somatic (body) cells that preserves chromosome number. It is preceded by S phase, when DNA is replicated.
- Chromosome vs. chromatid: after S phase each chromosome consists of two sister chromatids joined at the centromere. During anaphase those chromatids separate and are counted as individual chromosomes in the daughter nuclei.
- Cytokinesis physically partitions the cytoplasm, producing two cells.

Step-by-step reasoning with counts (example using a human cell):
1. Start: a diploid somatic mother cell with 46 chromosomes.
2. S phase: DNA replication produces sister chromatids; the cell still has 46 chromosomes but 92 chromatids.
3. Mitosis — metaphase/anaphase: sister chromatids separate; each set now becomes 46 individual chromosomes destined for each daughter nucleus.
4. Telophase + cytokinesis: nuclear envelopes reform and the cytoplasm divides, yielding two cells. Each daughter cell ends up with 46 chromosomes (the same number as the original mother cell) and with essentially identical genetic material.

Why the correct answer is correct:
- The result of mitosis plus cytokinesis is two cells that are genetically identical and are produced by an even partition of cytoplasm, so they are generally identical in size and genetic content.

Why the other options are incorrect:
- “Two cells, each with half the number of chromosomes as the mother cell”: describes meiosis, not mitosis.
- “Three cells…”: mitosis produces two, not three.
- “Two cells identical in genetic material, but one is smaller…”: cytokinesis normally yields two similar-sized cells; unequal sizes would indicate asymmetric division (not the standard outcome described).
- “Two cells, each with twice the number of chromosomes as the mother cell”: that would imply chromosome doubling without segregation, which does not describe mitosis.

Conclusion: The correct answer is “two cells identical in size and genetic material.” This matches the provided answer.
