Remark
This documents is a simply guideline for understanding colors breeding in the TRD, is for educational purpose only. It should be noted that four generations is simply a reasonable number to assume a recessive gene may have been eliminated based on its non-appearance. Four generations is not a validated number of generations that guarantees an undersirable recessive gene cannot be carried without appearance.
