Final answer:
Mendel's experiments involved traits that show discontinuous variation, also known as discrete traits. These traits are inherited in distinct classes, such as violet versus white flowers.
Step-by-step explanation:
Mendel's experiments involved traits that show discontinuous variation, also known as discrete traits. These traits are inherited in distinct classes, such as violet versus white flowers. Mendel's choice of these kinds of traits allowed him to see that the traits were not blended in the offspring. Instead, they were inherited as distinct traits.
