Scientific accident results in creation of six-legged mouse without genitals

A rare mouse embryo, which has six legs and no genitals, was created by scientists in an accident. This never-before-seen creation reflected how changes made to the DNA can have severe impacts on development. A team of scientists from Portugal's Gulbenkian Science Institute were trying to understand how a specific protein works in the middle stages of embryo growth. Embryos at the beginning are only a bundle of identical cells. When they develop, the cells specialise and start forming different …
