Definitions:

Meiosis I

The first division in meiosis, a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, important for sexual reproduction.

Meiosis II

The second division in meiosis, where the two cells produced in Meiosis I divide again without DNA replication, resulting in four haploid cells.

Meiotic Divisions

Meiotic divisions are the process of cell division in sexually reproducing organisms that reduces the chromosome number by half, resulting in the production of haploid reproductive cells.

Haploid Daughter Cells

Cells resulting from meiosis that have half the genetic material (chromosomes) of the parent cell, essential for sexual reproduction.
