Reduction division is:
Correct answer: C. Meiosis I
- A. Amitosis
- B. Mitosis
- C. Meiosis I
- D. Meiosis II
Explanation
Meiosis is a type of cell division that occurs in the reproductive cells of eukaryotic organisms. It involves two rounds of cell division, meiosis I and meiosis II, and leads to the production of haploid cells (cells with half the number of chromosomes as the parent cell). Meiosis I is the first round of division, during which homologous pairs of chromosomes separate, and the chromosome number is reduced by half. Therefore, meiosis I is a type of reduction division.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
