Definitions:

Prophase I

The first stage of meiosis I where chromosomes condense, pair up, and exchange genetic material through crossing over, essential for genetic diversity.

Homologous Chromosomes

Pairs of chromosomes in a diploid organism that are similar in size, shape, and gene content, one inherited from each parent.

Sister Chromatids

Sister chromatids are two identical copies of a single replicated chromosome that are connected by a centromere and eventually separated during cell division.

Daughter Cell

A cell that results from the division of a single parent cell, usually having the same genetic material as the parent cell.
