Measurements of hybrid fertility and a test of mate preference for two house mouse races with massive chromosomal divergence. Numbers are this really simple invention. 1 2.

Example: what is the square root of −9 ? For example to reresent twelve they would put two fives and two ones. But it’s so amazing to think about what they enable as a species.
