Answer:
Genetic variation helps a species evolve and avoid inbreeding, which are both beneficial for a species survival.
Step-by-step explanation:
Genetic variation is incredibly important for a species survival.
Firstly because it helps species avoid having to inbreed, which lowers survival chances. Think of it this way, if a certain disease only affects somebody with a certain gene, and you all have the same genes, it becomes incredibly dangerous for the species as they could all be wiped out with little chances of survival.
Genetic variation also introduces new traits to future offspring, which may be beneficial and help a species evolve and become better suited to survive. It enables natural selection, and only the best traits go on to reproduce.
