IT IS AN EXACT SCIENCE. Lol.

You tell me how it's not.

If I breed an albino mouse, with an albino mouse, I will get 100% albino babies.
That's pretty exact.

You clearly don't know anything about genetics, so please don't make comments about something you don't understand being un-poven, just because you can't understand it. That's the wrong way of doing things.

There are people who understand it, and understand the science of it.
I suggest that you learn more about it, before you going spouting off that it's un-proven and not exact.
