Why do you think genetic diversity is an advantage of sexually reproduction?

Genetic diversity is an advantage of sexual reproduction because it reduces the occurrence of unfavorable genetic traits and a variety of genes would lessen the chance of the extinction of a population due to environmental changes. The variation between a genetically diverse species will guarantee at least some of it survive when presented with different climates or challenges.
