This is Gregor Mendel. He was a monk who lived in Austria.

This isMendel’s garden.

Mendel grew peas. Many peas.

He liked peas a lot. Here are some of his jars of peas.

He knew peas reproduced sexually (with and egg and pollen), and he began to control what peas crossed with other peas.

“Funny,” he thought. “Some of my peas are tall. Some are short.”

“If I cross a tall pea with a short pea, I get only tall peas.”

He started countingall of the short peashe got, and all of the

tall peas.

He seems very puzzled

Gregor Mendel is called “The father of modern genetics” because of his work breeding and analyzing peas in the 1800’s. He looked carefully at his numbers, andthought hard about:
