My Example Organism: Polar Bears Trait: Size Goal: I would like to breed very small polar bears. Procedure: 1. Call all the zoos in the world and ask them for the weight of their adult polar bears. 2. Take the 20 smallest bears, 10 male and 10 female and breed them together. 3. In the next generation, feed the bears all the same amount and, once the bears have reached maturity, again select the 20 smallest bears. 4. Do this for each generation until polar bears reach desired size.
