Final answer:
The principle of individual differences states that the rate and magnitude of adaptations to training will be limited by our differing genetics.
Step-by-step explanation:
The statement is True. The principle of individual differences in biology states that the rate and magnitude of adaptations to training will be limited by our differing genetics. This means that each individual's genetic makeup plays a role in how they respond to training and the extent to which they can adapt to it. For example, some individuals may have a genetic predisposition for aerobic fitness, allowing them to respond well to cardiovascular training, while others may have a genetic predisposition for strength training. These individual differences can affect the rate and magnitude of adaptations.
