Answer:
The three stimuli that cause the plants to exhibit tropism are:
1. Touch: This stimulus triggers thigmotropism, which is the turning or bending of the plant and tendrils in response to the touch.
2. Light: This stimulus triggers phototropism. It is how the plant reacts toward the direction of the light source. In this case, the stem may bend in response to the direction of the light.
3. Gravity: This stimulus triggers phototropism gravitropism, which is responsible for the downward growth of roots into the soil.

Explanation:
Mendel's law of independent assortment is about the random distribution of alleles of one gene during anaphase-I. It states that alleles of two or more genes segregate randomly to the poles of the cell. For example, the segregation of R and r alleles to the two poles of the cell would not affect the segregation of the T and t alleles. This random and independent segregation of alleles of different genes during anaphase-I produces new gene combinations in the progeny.
