Reminds me of the Ambystoma salamanders that reproduce via kleptogenesis. They are all female, and they "steal" sperm from males of 3 or 4 related species. Most of the time they discard the male's genetic material, but sometimes they incorporate it, which results in embryos that have multiple sets of chromosomes. It's wild. The offspring can contain genetic material from up to 4 different parental species.
