How come recessive genes don’t die out?

Question

I’ve googled it, but all the answers are telling me is that it’s been way too long since those genetics lessons in middle school

Answer 1

Because recessive genes are still passed along to the next generation with the same frequency that dominant genes are passed along. The only way in which natural selection will select against a particular allele is if carrying it decreases the odds of that individual reproducing and passing along their genes. In other words, natural selection only cares if a recessive gene is harmful even when the dominant gene is present, and the harm has to happen before the age of reproduction.
