Due to a recessively inherited trait, some plants fail to produce chlorophyll and therefore are white rather than green. If we locate a pea plant that is heterozygous for this trait, self-pollinate it, harvest the seeds, and then plant the seeds, what are the likely phenotypes of the resulting offspring?
