farmers in areas with rocky soil had difficulty plowing their fields. they noticed that heavier horses could plow the fields more efficiently than smaller horses. over many generations, farmers were able to increase the average weight of their horses without changing the horses’ diet and housing very much. during the same time period, other inherited traits such as eye color and coat color did not change.\n\n• which inherited trait in horses was most useful to the farmers?\n• what method did the farmers use to change that trait to plow fields more efficiently?\n\nenter your answer in the box provided.

Answer

Brief Explanations:

  1. The text mentions heavier horses plow fields more efficiently, so weight is the useful inherited trait.
  2. Farmers likely used selective - breeding. They chose to breed heavier horses over generations to increase the average weight of the horse population for better field - plowing efficiency while other traits remained unchanged.

Answer:

  • The most useful inherited trait was weight.
  • The method farmers used was selective breeding.
