Timothy inherited attached earlobes because his maternal grandfather had homogenous genes for attached earlobes. Along with this, the woman that his grandfather married and had offspring with either had homogenous genes for attached earlobes, or had mixed genes so both of his grandparents passed on the recessive trait for attached earlobes.
