Can Inheritance Be Controlled?

  • What if you are a gardener who likes big, showy daffodils? You could produce the kind of flower you like by crossing two of the largest daffodils in your garden, then crossing two of the largest offspring from that cross. If you did this over and over again, after several generations you might find you've developed the largest daffodils anyone has ever seen.

    Growers have used selective breeding to develop many different color and shape variations in flowers.

  • The process of crossing plants or animals to produce offspring with certain desirable traits is called selective breeding. People have used selective breeding for centuries to produce better food crops, hardier domestic animals, and prettier flowers.

Luther Burbank developed many new varieties of fruits and vegetables. He used selective breeding in his work. Farmers use selective breeding to produce drought-resistant wheat, sweeter corn, or crops that are resistant to damage from insects. Cattle are bred to produce more milk or leaner meat.

Most of the dog breeds we know today were developed by selective breeding, including sheepdogs. Beagles, terriers, and other small hunting dogs were bred for tracking small game, such as rabbits and foxes. These dogs have an excellent sense of smell, and their small size enables them to follow a hunted animal into its burrow. Siberian huskies are large dogs bred for pulling sleds across the snow. Huskies have thick fur that helps keep them warm and strong muscles for pulling heavy loads.

Sheepdogs have been selectively bred for the ability to herd sheep
