Web10 de jan. de 2024 · Genetic variation can arise from gene variants (also called mutations) or from a normal process in which genetic material is rearranged as a cell prepares to divide (known as genetic recombination). • Genetic variations that alter gene activity or protein function can introduce different traits into an organism . WebThis trait is a result of a mutation from thousands of years ago. The mutation causing the trait was beneficial and heritable, so it spread throughout the human population and many of us today have this trait!
