Genes are more likely to predict breast basis, not actual size. A great deal of times women are born with actual breast size, but it can change throughout their lifespan. Most extremities, such as arms, legs, feet, and ears, grow to a certain point and then stop. On the other hand, breasts are totally different.
The shape and size of the breasts are determined genetically, but they can change as a result of pregnancy and lactation, intensive workouts, and sudden weight fluctuations.
