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

In Mendel’s experiments, when pea plants with two characters such as colour of seed and shape of seed were bred together, plants with Yellow coloured Round seeds were crossed with plants having Green coloured wrinkled seeds. The F1 progeny showed all plants with Yellow coloured Round seeds, showing that these were the dominant characters. However, when self-pollinated for second generation, certain progeny plants also exhibited new combinations like Yellow coloured Wrinkled seeds, or Green coloured Round seeds. This shows that both the characters were inherited independently.
