Why your DNA is only half the story of who you are
In short: Explore the complex interplay between heredity and surroundings. This video examines how environmental factors influence trait expression and shape the visible variation within a population.
The distribution of traits in any population is not determined by genetics alone. While genes provide the blueprint, environmental factors play a critical role in how those traits are expressed.
Understanding this relationship is essential to grasping the mechanics of inheritance and the broader patterns of biological variation.
