By choosing the traits we like the best in plants or animals and then breeding those better traits, we are selectively breeding. An example would be the dogs we have today. My Siberian huskies were selectively bred over the years from the wolf years ago to create a domestic dog that could socialize with humans. Wolves are very large (over 100 pounds), yet my Siberian huskies average only 60 pounds (much better for a household). The smaller size was a trait selected to be bred.
