Sperm Made From Female Bone Marrow, Men Obsolete?
Shaitan Apistos writes "British scientists have discovered a way to turn female bone marrow into sperm, allowing women to reproduce without the need of male companionship. All children born of this method would be female, due the lack Y chromosomes, and there is high chance of birth defects. Eggs also can be created from male bone marrow, but men looking to reproduce would still need to find a surrogate mother to handle the gestation period. I'd like to take a moment to welcome our new amazonian overlords and remind them that men are still very good at mowing lawns and fixing cars."
These techniques that farmers use have completely screwed up many breeds. For example, a lot of purebreed dogs have very bad problems with their knees, which is mostly due to "setting" traits by mating siblings done hundreds of years ago.
