1. an example of selective breeding is crossing a poodle and a labor-doodle that have desired traits. usually this is practiced on by plants and animals.
2) Directional selection: this type of selection works to select the extreme of one trait. For example, in a population of plants, flowers with the brightest color might be selected for in order to attract the most pollinators. 3) Disruptive selection: this type of selection selects against the mean of the population.)
