What best defines genetic diversity? the variety of traits a species has. a group of organisms of one species. all the different plants, animals, fungi, and microorganisms. all the different habitats and ecosystems found around the planet.

Genetic diversity is best defined as the variety of traits a species has.

Genetic diversity is increased in sexually reproducing organisms by events such as crossing over in Prophase I of meiosis, independent assortment of chromosomes at the metaphase plate, and random fertilization. This creates a unique combination of alleles from the mother and father passed to the offspring, which increases genetic diversity, or the varying traits that different members of a species exhibit.

Hope this helps!
