This shows that many people who carry the freckle gene do not show it in their adolescence, but show it later under exposure to the sun. Some pregnant women did not have freckles before, but hormonal changes during pregnancy stimulate the formation of freckles. These women are recessive carriers of the freckle gene.

2. Long-term exposure to the sun. The sun's ultraviolet rays make the skin's melanocytes active.
