Beth's red hair can be attributed to genetics. The gene responsible for red hair is recessive, which means both of her parents need to carry this gene to pass it on, even if they don't have red hair themselves. This gene influences the production of melanin, specifically pheomelanin, which gives hair its red pigment. It's a beautiful expression of her genetic makeup, showcasing the diversity and complexity of human traits.
