Since llamas have sexual reproduction, the offspring have the potential to be genetically diverse. how can genetic diversity be an advantage when compared to asexual reproduction?

Genetic diversity is important because it helps maintain the health of a population because a diverse set of alleles that can be valuable in resisting diseases, pests and other stresses. If the environment changes, a population that has a higher variability of alleles will be better able to evolve to adapt to the new environment and therefore survive longer. Hope this helps!
