Step 1: Understanding the Concept:
Meiosis is a specialized reductional nuclear division occurring in sexually reproducing eukaryotes.
Step 2: Detailed Explanation:
Both mitosis and meiosis involve spindle microtubule formation, genetic regulation, and cytokinesis.
The defining, unique attribute of meiosis is chromosome reduction: a diploid parental germ cell ($2n$) undergoes one round of DNA replication followed by two successive nuclear divisions (Meiosis I and Meiosis II), producing four haploid daughter cells ($n$) each carrying exactly half the chromosome complement of the mother cell.
Step 3: Final Answer:
Therefore, reduction of daughter cell chromosome number by half is unique to meiosis.
