Which of the following is the specialized kind of cell division that reduces the chromosome number by half, resulting in the production of haploid daughter cells?
Meiosis
Meiosis is a specialised type of cell division that occurs in the reproductive cells to produce gametes.
During meiosis, a single diploid parent cell divides twice to form four daughter cells, each having half the number of chromosomes of the parent cell, making them haploid.
This reduction in chromosome number is essential to maintain a constant chromosome count across generations after fertilisation; in contrast, mitosis produces identical diploid cells and does not halve the chromosome number.
Hence, the division that halves the chromosome number and produces haploid daughter cells is meiosis.
