Final answer:
The differences in males' and females' motor skills are primarily a combination of innate and environmental factors. Both genetics and the environment play a role in shaping motor skills.
Step-by-step explanation:
The differences in males' and females' motor skills are primarily a combination of innate and environmental factors. Both genetics and the environment play a role in shaping motor skills. While genetic factors provide a foundation for motor skills, external factors such as parenting styles, forms of play, and cultural expectations also influence the development of motor skills. Therefore, it is not accurate to say that differences will eventually disappear, as both innate and environmental factors continue to contribute to individual differences in motor skills.
