meiosis

The process of cell division in sexually reproducing organisms that reduces the number of chromosomes from diploid to haploid, as in the production of gametes.

Rhetorical understatement.

Diminution; a species of hyperbole, representing a thing as being less than it really is; understatement; see also litotes.

The cellular process by which a diploid progenitor cell forms haploid gametes, including a division of one diploid cell into two cells, each with one of the homologous sets of chromosomes.

A figure of speech whereby something is made to seem smaller or less important than it actually is.

Cell division of a diploid cell into four haploid cells, which develop to produce gametes.

understatement for rhetorical effect (especially when expressing an affirmative by negating its contrary)

(genetics) cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants)
