Question
The appearance of new trait combinations (like tall plants with wrinkled seeds) in the F2 generation of a dihybrid cross shows that
the two traits (height and seed shape) are always linked and inherited together
the two traits are independently inherited
the traits blend together to form a completely new trait
no inheritance pattern can be determined
Answer
the two traits are independently inherited
Detailed Explanation
New combinations of traits (not seen in either parent) in F2 progeny demonstrate that the tall/short trait and the round/wrinkled seed trait are inherited independently of each other.
