    • What is selective breeding in animals
      It is the process of breeding individuals with desired characteristics over successive generations to produce offspring with those traits
    • Why are several parents with desired traits often chosen in animal selective breeding
      To avoid breeding siblings in the next generation, reducing the risk of inbreeding
    • What are some characteristics animals are selectively bred for
      Cows, goats and sheep that produce lost of milk or meat
      Chickens that lay large eggs
      Domestic dogs with a gentle nature
      Sheep with high quality wool
      Horses with fine features and fast pace
    • Give an example of an animal that has been extensively selectively bred
      Domestic dogs all of which are descended from wolves and have been bred for various traits
    • What us the goal of artificial selection
      To develop populations with features useful to humans nor necessarily for the survival of the individual
    • How is selective breeding similar in plants and animals
      Both involve breeding individuals with desirable traits and repeating the process over many generations
    • How does natural selection differ from artificial selection
      Natural selection =
      happens naturally
      helps organisms develop traits suited for survival in their environment
      takes longer time to occur
      Artificial selection=
      Controlled by humans
      produces traits beneficial to humans not always for survival
      Happens faster due to human intervension
