How did Man Find out about Heredity?

Every living and growing thing in the world, whether animal or plant, produces young of it s own kind or species, and no other. This takes place because of heredity. However, the offspring of any two parents need not all be the same in their traits, such as looks, coloring, and physical and mental condition.

Their differences also result from heredity, hereditary traits which from something inside the baby at the very second that his life begins. The first facts from which the whole modern science of heredity was developed were discovered by an Austrian monk, Gregor Mendel, in the mid-nineteenth century.

Mendel was experimenting with sweet peas in his garden. He discovered that in the seeds from parent plants, there were a large number of different factors that always worked by certain rules to control what a plant growing out of the seeds  would look like.

We now call these factors "genes". But it was not until 1900, 16 years after Mendel’s death, that other scientists saw how important his findings were. They called his discoveries "the Mendelian Laws".
