Unlike animal breeders and human geneticists, plant breeders rarely use pedigree charts in their work. Which is most likely the reason that plant breeders use other methods for analyzing results instead of constructing pedigree charts? Plants have many more offspring than most animals have. Plants have too many important traits to show in a pedigree. Plants change only through mutation, not breeding. Plants change too much in each generation to show in a pedigree.
