This increases genetic diversity

Explanation:

It allows for a better chance of survival chance for the population as a whole. Think of every person had blonde hair and a disease came through and killed every person with blonde hair everyone should be dead and our population would not continue. But if there is a mix of brown and red and blonde then if all the blonde people die the population as a whole will continue.
