Genetics play a significant role in determining our traits, with half of our DNA inherited from our mother and half from our father. While many traits come from both parents, some unique genetic traits are exclusively inherited from our fathers. These traits include the shape of our teeth, hair growth patterns, baldness, height, biological sex, and even the ability to become a father. Understanding these genetic traits can provide insight into ourselves and our family history, shedding light on the complex world of genetics.
