Sexual reproduction brings about a randomly selected mixture of genes from both parents. Human genetics consists of 23 pairs of chromosomes, each containing various genes. Because chromosomes come in pairs, there is always a choice of genes. So the gametes from one parent are not all genetically identical. If they were, then all the children from any given two parents would be the genetically identical. But the genes get re-shuffled. Sexual reproduction is all about genetic variation, that's why it exists. With varied genetics, there is a greater chance that there will be offspring who are suited to changing conditions in the environment. This would be true even for ugliness. You cannot be sure that there will never be a situation in which it will be more advantageous to be ugly rather than beautiful.
