I was not referring to sexual variation. I was responding to this:Are you missing our explanation of sexual variation?Mutation needed to get the variation in the first place.
"Of your 23 pairs of chromosomes, each pair is made up of one from each parent. A mix of both. You are a variation of your parents. No mutation needed."
Did you mean to quote someone else?
It is not really "combining" their DNA. It is getting complementary chromosomes from each. And the differences in each parent are indeed derived via mutation, ultimately.Newborns differ both from their parents and from each other, not from mutation, but from genomes formed by combining DNA from two parents.
