Edward East investigated whether or not Mendelian genetic models could be applied to the study of quantitative traits by studying corolla length in longflower tobacco. He began with two pure-breeding strains, one with long corollas and one with short corollas. One of his central predictions was that, if the Mendelian model applied, the range of variation in his F2 hybrids would not extend all the way to the original parental phenotypes. Which of the following best explains why?
