Artificial selection is the type of selective breeding.
Selective breeding is process of breeding parents with distinct characteristics to produce offspring with more desirable characteristics.
Most of the time the breed of dogs were formerly selected for particular purposes, such as hunting or guarding which needs strong physical endurance. Hence, Selective breeding is evolved by human selection. For example racehorses, having particular traits are desirable in different breeds of dogs that compete in dog shows. Artificial selection, is selective breeding that is imposed by an selective process, in order to get the phenotype of desirable features.

Answer: There re two different types of phenotypes in the offsprings that is Round yellow and Round green.
Explanation-
As per the Mendelian inheritance, Round shape and yellow color of pea are dominant over wrinkled shape and green color of pea.
According to the question, genotypes of parents are- RrYy ( heterzygous for round and yellow) and RRYy ( homozygous for round and heterozygous for yellow).
The first parent can produce four different gametes that is RY, Ry, rY, ry whereas the second parent will produce only two types of gametes that is RY and Ry.
When they are crossed, they will produce two different phenotypes in the offsprings.
