The fact that the correlation for identical twin pairs is almost twice that of fraternal twin pairs suggests that genetics play a strong role in pubertal timing. Additionally, the higher correlation for fraternal twin pairs compared to singleton siblings suggests that there may also be some environmental factors at play, but the overall pattern suggests that heredity is the primary cause of physical maturation.
