Afarmer has a herd of sheep with an average weight of 200 pounds. the heaviest sheep weigh around 350 pounds. he wants to know if the weight of the sheep is genetic. so, he breeds two of his heaviest sheep. the offspring grow up to weigh 300 pounds.

Through this breeding, the farmer is able to support his claim that the large size of some of the sheep may be genetic. This is due to the fact that when the farmer bred the sheep, the offspring was far larger than the average sheep in the farmer's herd. 
A genetic trait is one that is passed down from parent to offspring, while one acquired by the organism through its environment is not passed to its offspring.
