The simplest possible wind-energy turbine consists of three crucial parts: 1  Rotor blades-The blades are basically the sails of the system; in their simplest form, they act as barriers to the wind (more modern blade designs go beyond the barrier method).
Bay horses with allele AA but not A+ are bay, with a black mane, tail and points. Their bodies may be reddish-brown (as in standard, blood and mahogany bays), orange-red (as in copper bays) or yellowish (as in golden bays) and may have a black cast. Horses with allele A+ are light or wild-type bay.
The same may be the case with wild bay, as well. All of the other colors you see in horses are actually the result of other genes modifying the appearance of the three base colors: black, chestnut or bay/brown. The horse is still chestnut, black or bay/brown at its base color. There is artwork depicting a medium shade of each color on each page of our Color Gallery.
