Final answer:
Learned Traits are not heritable because they are acquired through experience and are not genetically passed from parents to offspring, unlike Physical, Physiological, and Behavioral Traits.
Step-by-step explanation:
The trait that is NOT an example of a heritable trait variation found in a population is Learned Traits. Heritable traits are those that can be passed from parents to offspring through genetic information. These include Physical Traits, such as fur color in dogs; Physiological Traits, like the blood types; and Behavioral Traits, which may be influenced by genetics such as innate behaviors in animals. Learned traits, however, such as reading or riding a bicycle, are acquired through experience and are not encoded in an individual's DNA, thus they cannot be inherited from one generation to the next.
