Definitions:

Homologous Chromosomes

Pair of chromosomes that have the same gene sequences, each derived from one parent.

Meiosis

A type of cell division that reduces the chromosome number by half, resulting in the production of gametes or spores in sexually reproducing organisms.

Sex Chromosomes

Chromosomes that differ between the sexes; in humans, these represent the X and Y chromosomes.

Autosomes

Chromosomes that are not sex chromosomes; humans have 22 pairs of autosomes that carry the bulk of genetic material responsible for determining traits and functions.
