Who is Gregor johann Mendel?
qaws [65]
I’ll give you a short overview of what I know.

He was a scientist, biologist, and wrote many books. He was specifically known for creating the science of genetics.

Mendel was born in 1822 into a poor farming family and then died January of 1884. He was an Austrian monk who discovered the basic principles of hereditary through experiments in his very own garden!

I’m sorry. I don’t believe this defines him. You can’t really define anyone in this short of a paragraph. To really know him, I’d have to do deeper research.
As for now, I hope this helps out. This probably just scratches the surface of who he really was. Have a great night!

All my best,
