The resulting offspring from a purebred dominant and a purebred recessive pea plant is called a(n):

The resulting offspring from a purebred dominant and a purebred recessive pea plant is referred to as a hybrid because it represents a combination of two different alleles for a specific trait. In genetics, a hybrid organism is one that has inherited different genetic information, or alleles, for a given trait from its two parents. In this case, the purebred dominant plant contributes a dominant allele, while the purebred recessive plant contributes a recessive allele. The offspring will display the dominant trait because dominant alleles mask the effects of recessive alleles.

A purebred mix and mutt do not specifically apply to the context of plant genetics. A purebred would indicate that the plant has two identical alleles for a specific trait, and the term F2 generation refers to the second filial generation of offspring that result from a cross of two F1 hybrids, not directly from the original cross between the purebred dominant and recessive plants. Thus, describing the offspring as a hybrid is accurate and reflects the genetic diversity produced by the cross between a dominant and a recessive parent.
