Definition
Crossing over is a process that occurs during meiosis where two chromosomes pair up and exchange segments of their genetic material. This leads to a mix of parental traits in offspring, contributing to genetic diversity.
A type of cell division that results in four daughter cells each with half the number of chromosomes as the parent cell; it's how sex cells are produced.
