1. Two pea plants, hybrid for a single trait, produce 60 pea plants. approximately how many of the pea plants are expected to exhibit the recessive trait?

In this case, you are going to cross two hybrid/heterozygous plant. When you cross two heterozygous, the result would be: 50% heterozygous, 25% homozygote dominant, 25% homozygous recessive.

Then, the number of the plant with recessive trait would be: 60 * 25% = 15 plants

2. a student crossed wrinkled-seeded (rr) pea plants with round-seeded (RR) pea plants. only round seeds were produced in the resulting plants. this illustrates the principle of dominance

There are dominant and recessive traits in genetic. The dominant trait will always be expressed if it is present. That means if the plant having 1 dominant and 1 recessive allele (heterozygous like in this case), it will express the dominant trait.
