Freckles are a result of genetics and too much sun exposure. For these combinations, the same genetics apply, the parents have to offer two recessive genes for this trait so the child can possess both red hair and green eyes. Your parents passed these genes down to you, just as their parents passed down their genetic makeup to them. (2008).
