    TV-PG
    It might surprise you to know that most human characteristics (including eye color) aren’t governed by a single gene. Nor do dominant genes always become more common over time. As you’ll discover, we owe these and other misconceptions about genetics to the Punnett squares you first encountered in high school biology.
