Heredity is BEST described as __________.

Heredity refers to the genetic traits and characteristics inherited from parents that can influence an individual's physical abilities, including aspects of skill-related fitness such as agility, balance, coordination, power, and reaction time.

The notion that heredity encompasses natural abilities that cannot be changed reflects the understanding that while individuals may possess inherent strengths or talents due to genetic factors, this does not mean those traits are entirely fixed. For instance, someone may have a genetic predisposition that gives them a natural advantage in certain skills, but practice, training, and environmental influences can significantly enhance or modify those abilities over time.

It is also important to understand that while heredity lays the foundation for physical skills, environmental factors, training, and personal effort can lead to significant improvements in fitness. Nevertheless, the genetic aspect provides a baseline that influences how well individuals may perform in skill-related activities. This reinforces the idea that certain natural abilities are indeed linked to hereditary traits, supporting the accuracy of the assertion that heredity can be described as natural abilities that are influenced by genetics.
