"Baby mice fathered by mice receiving a donation of spermatogonial stem cells from mice expressing green fluorescent protein."
Only half the baby mice show the green color. This is because each spermatogonial stem cell has only one copy of the gene for green fluorescent protein. When the spermatogonial cell divides, only half the cells that result from it have the gene for green fluorescent protein.

Sometimes I just wonder why.
On another why? If you have wondered why the Middle East has been blowing up, I would direct you to a wonderful blog post about Tunisia and its place in the simmering region. I do mean simmering since the post is mostly about food... or is it?
Sometimes the response to a "why?" is just not something you would ever conjure from the depths of your own experience.

when we run out of oil we will need to light our houses with florescent mice!!! Do not mock the power of science!
Florescent mice keep florescent kitties happy... I'm waiting for florescent rats, so I can track them at night...
