An anaconda snake at the Boston New England Aquarium produced 18 babies without the help of a male. It happened through a process called parthenogenesis. The sets of genes came from her eggs. The egg first clones itself before self-fertilizing. All of her offspring were clones, which doesn’t always happen with parthenogenesis. But in this case the babies were all identical to her. Only two survived. They are being taken care of at the aquarium.
