You paid 1,000,000 to purchase a black Angus bull named Maxwell that was advertised as a pure-breeding black Angus cow (BB; B = black and b = brown; B is dominant to b).
 
  You mated Maxwell with Bessie, who also was advertised as a pure-breeding black Angus cow (BB); as you expected, all of their offspring were black. Several years later, you mated a pair of these offspring several times (F1  F1) and found that approximately 25 of the F2 progeny were brown instead of black. What were the actual genotypes of the original cross (Maxwell  Bessie)?
  A) BB  BB
  B) Bb  BB
  C) Bb  Bb
  D) BB  bb
  E) bb  bb
