Examples

“Plant⟳ breeding is always a numbers game.[…]The wild species we use⟳ are rich in genetic variation, […]. In addition, we are looking for rare alleles, so the more plants we try⟳, the better. These rarities may be new mutations, or they can be existing ones that are neutral—or are even selected against—in a wild population. A good example is mutations that disrupt seed dispersal, leaving the seeds on the heads long after they are ripe.”
