My mother and my sister are both E cups. Why do I only have C cups?

Your mother and sister are both white and cannot be inherited. It may be that its own development has not yet arrived, and it must be mature, or it may reach 1M times. It will take a long time. According to everyone's physical condition, as well as the nutritional collocation in all aspects of the system, the usual diet and daily life, and various details in life will definitely determine their physical condition, because sometimes they eat different things and their development is the same. Not everyone likes big, big and big troubles.
