PUREBRED traits are when a pea has

one of each type of gene for a trait (one dominant and one recessive)

two of the same genes for a trait (both dominant or both recessive)

PUREBRED traits refer to the presence of two of the same genes for a particular trait, either both dominant or both recessive. This means that if a pea is purebred for a certain trait, it will consistently pass on the same version of the gene to its offspring.
