You are given two true-breeding groups of guinea pigs. The guinea pigs in the first group have brown coat color and long tails; the guinea pigs in the second group have a white coat color and short tails. When you produce an F₁ generation, by crossing these two groups, you see only guinea pigs with brown coat color and long. tails. When you produce an F2 generation, by crossing F₁'s together, you see some guinea pigs with brown coat color (75%) and some guinea pigs with white coat color (25%). You also see some of the guinea pigs have short tails (25%) and others (75%) have long tails. If the single alleles responsible for coat color and tail appearance sort independently, what percentage of the brown guinea pigs are expected to have long tails?
