Basic information
Once upon a time (1865's), in an Czech
monastery, there lived a monk named
Mendel, Gregor Mendel.
Monks had a lot of time on there hands and
Mendel spent his time crossing pea plants.

SCIENCE
Basic information
As he did this over and over again, he
noticed some patterns to the inheritance of
traits from one set of pea plants to the next.
By carefully analyzing his pea plant numbers
(he was really good at mathematics), he
discovered three laws of inheritance.
