How do Mendel's experiments show that traits are inherited independently?

Explanation

Mendel crossed pure breeding tall plants having round seeds with pure breeding short plants having wrinkled seeds. The plants of `F_1` generation were all tall with round seeds indicating that the traits of tallness and round seeds were dominant.
Self breeding of `F_1` yielded plants with characters of 9 tall round seeded. 3 tall wrinkled seeded. 3 short round seeded and one short wrinkled seeded.
Tall wrinkled seeded and short round seeded plants are new inherited independently
