backcrossing!

For non-recessives, he bred plants at a monestary from groups that had never shown a recessive.
Unlike PEOPLE, one pea plant can put out 300 young without a problem. If he planted 300 seeds from one plant, and they all had the same trait, and those plants, crossed with each other, still put out the same trait-he assumed they were pure, and statistically, they were.
Since he was in a monestrary, doing what his order considered God's work, he had time to keep at it.

He crossed until all the offspring had the trait, creating a "pure-breeding" strain. We call them homozygotes.

He didn't. His data was probably fudged to fit his theory. His results were too perfect to be statistically believable.

By observation.
Some were purely, yellow,or green.
Some were wrinkle,or smooth.
It was purely by luck.

Not artifical selection
