Genetics do play a role, but because captive RES are fed (and sometimes overfed) a nutrient dense diet, many are about 4 inches (shell length without the curve) at a year. However, if at a year a RES is smaller (3.5 or even closer to 3 inches), as long as the turtle is otherwise healthy, this is not necessarily bad (and may, in fact, be preferable). Growth much over 4 inches is usually due to a diet too high in protein and/or overfeeding (which isn't good).
