Answer to Question #8454 in Biochemistry for Marissa

Question

Before Gregor Mendel's work with garden peas, he had to ensure what about the plants?

Answer 1

Before Mendel started his experiments, he had to ensure the plants were purebred. He breed a
species several times with its own kind to "breed out" any (or most) foreign genes of that
species (similar like what a dog breeder dose to get a "purebred" dog).
