It has been accepted wisdom for decades that most animals create germ cells ― those cells that produce the eggs and sperm organisms need to pass on their genes ― in the same way.

(Phys.org)—It's strange to think that there was a time when molecular cell biology was considered by professionals of other scientific specialties as disreputable or laughable. But the motivation for much cellular biology ...
New work from Carnegie's Allan Spradling and Lei Lei demonstrates that mammalian egg cells gain crucial cellular components at an early stage from their undifferentiated sister cells, called germ cells. This mechanism had ...

Life begins with an egg and a sperm: that much is clear. But how do these "germ cells" form, and how do they pass genetic traits from one generation to the next?
