Crossing over is one of the most important events in meiosis because ____.

A) it produces new combinations of alleles on chromosomes
B) homologous chromosomes must be separated into different daughter cells
C) the number of chromosomes allotted to each daughter cell must be halved
D) homologous chromatids must be separated into different daughter cells
E) it decreases genetic diversity

Crossing Over

Crossing over is a genetic process that occurs during meiosis where homologous chromosomes exchange segments, leading to genetic diversity in gametes.

Alleles

Variants of a gene that determine distinct traits that can be passed from parents to offspring.

Genetic Diversity

The total number of genetic characteristics in the genetic makeup of a species, contributing to its ability to adapt to changing environments.
