T2 - Which observation of dihybrid crosses led to Mendel's law of independent assortment

• Particular individual traits persisted for many generations
• Many combinations of traits were always inherited together
• Some combinations of traits were not passed onto offspring
• The presence of one trait didn't affect the presence of another
