Answer:

Genetic variation is very important in the genetic code because we and all animals would be incredibly susceptible to genetic diseases if it wasn't varied.

Explanation:

Genetic disease is mostly caused by familiarity in the genetic code. I cant remember the year, but sometime in the late 1900s an unknown disease was killing hundreds of thousands of people in the US, and was spreading like wildfire. Nobody knew how to stop it from spreading because they had no idea how it was spread. It turns out it was spread through mating, which stemmed from a dominate genetic problem. Eventually the source of the spreading was found, and people ceased to mate with multiple individuals, ceasing the massive spread of the disease. Without the genetic variation in animals and humans, we would constantly be susceptible to these things.
