By using genetic material from two male mice, researchers successfully created pups that survived to adulthood, offering insights into unisexual reproduction in mammals.

Cyan-labeled cells are clustered at the top of an ovoid structure, underneath them are yellow-labeled cells and under them red-labeled cells, and surrounding all three layers are white labeled cells.
