In guinea pigs, disheveled (rosette) coat B dominates over smooth b, and black C over white c. Black guinea pigs with rosette hair when crossed with each other gave two offspring – rosette white and smooth black. What offspring can be expected from these pigs in the future?

From this pair of gilts, one can expect rosette black, rosette white, smooth black and smooth white offspring in a ratio of 9: 3: 3: 1.
