Definitions:

Haploid

Referring to a cell or nucleus containing a single set of unpaired chromosomes, as seen in gametes (sperm and egg cells) of sexually reproducing organisms.

Meiosis

is a type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell.

Chromosome Segregation

The process during cell division in which chromosomes are equally distributed into two new nuclei, ensuring each daughter cell receives an identical set of chromosomes.

Meiosis

A specialized type of cell division that reduces the chromosome number by half, resulting in the production of sexually reproductive cells, such as sperm and eggs.
