Video transcript. - We're told that in a population of pea plants, some plants have round seeds and others have wrinkled seeds. The gene for seed shape in this population has two possible alleles. Remember, alleles are just versions of the gene. One allele or one version is for round seeds, which we're denoting capital R, and the other allele ...
