Half their genes come from the egg, half from the sperm cell in animal-style sex.

Bacteria pass their genes with abandon as one bacterium donates its genes to another. No fifty-fifty contribution exists for bacteria. Bacteria literally pick up genes, usually a few at a time. The donor may mate when "he" physically contacts "her," a live bacterial recipient. "She" looks just like "him." Or gene uptake may be casual necrophilia; the recipient may just grab genes shed earlier when some dead donor left them in the water.Genes snatched from the environment may be for making vitamins, gas venting, or other traits that increase chances of survival. Sometimes the genes code for proteins
