once Vo Correct terms long One advantage of pea plants for the study of genetics is that they can be fertilized short An advantage of the pea plants that Mendel studied was that there were many true-breeding varieties so that he could demonstrate that the results he heterozygotic obtained for one trait were with another purebred Pea plants are useful as model organisms because they have a relatively time generation Mendel could study a single variable at a time since reproducible he began with plants Self Reset
