What is the most important link connecting heredity and evolution?
Answer and explanation
Correct answer: Inherited variation
The governing concept is that heredity transmits genetic information, while variation produces differences among individuals. Only variations that are genetically inherited can be passed to future generations and become more or less common through natural selection, genetic drift, or isolation. Therefore, inherited variation directly connects heredity with evolution. Acquired habits, food preference, and cleanliness are not, by themselves, inherited genetic changes.
