5. What did Mendel learn about the passage of traits/variation when using Purebreeds?

Fundamental theory of heredity

Mendel found that paired pea traits were either dominant or recessive. When pure-bred parent plants were cross-bred, dominant traits were always seen in the progeny, whereas recessive traits were hidden until the first-generation (F1) hybrid plants were left to self-pollinate.
