Yes, skin color is determined by your DNA. The genes you inherit from your parents play a significant role in your skin tone. A recent systematic study found 169 genes involved in human skin coloration. These genes influence the production and distribution of melanin, the pigment responsible for skin color.
For example, people with more melanin in their skin have darker skin tones. The amount of melanin produced varies due to genetic variations, and this is why people have different skin colors. While skin color is primarily determined by genetics, environmental factors like exposure to sunlight can also influence skin tone.
Here are some key points to understand:
- Genetics play a major role in skin color. You inherit genes from both parents, and these genes determine the amount of melanin your body produces.
- Sunlight exposure can modify skin color. Tanning is a temporary change in skin color due to increased melanin production triggered by UV exposure.
- Skin color is a complex trait. It is influenced by multiple genes working together, and there is a wide range of variation among individuals.
