Answer
Some species that have used selective breeding to result in a distinctive burr-breeding variety include tomatoes and livestock. Tomatoes are "bred" (genetically altered) for their color, size, flavor, and hardiness. Tomatoes are "bred" to be tougher are more likely to survive shipping without bruising. Additionally, livestock animals are often selectively bred. Chickens that are bigger have more meat bring in more profit. Large chickens are therefore bred with large chickens to produce large chickens. To verify that each of these varieties descended from a common ancestor, genetic testing should be carried out. The DNA sequences from each organism can then be examined. DNA sequences will be more similar in organisms that are more closely related. DNA can therefore be compared to identify relatedness between generations.
