I believe they are controlled by the Au gene, which is more prevelant in women. This gene also has an influence on other area's of the female appendage.
Au gene  you sly dog! Must be related to the Ag and Pt genes. Female appendages, eh? Let's see- would primarily affect fingers, wrists, neck, possibly toes, but in more recent times- tongue, lips, nostrils, eyebrows, belly buttons, nipples and other areas?
I wanted to know about the importance of our ear lobes..
Whether the earlobe is free or attached is a classic example of a simple genetic dominance relationship; freely hanging earlobes are the dominant allele and attached earlobes are recessive. Therefore, a person whose genes contain one allele for free earlobes and one for attached lobes will display the freely hanging lobe trait.
Evolution also saw the need for 1" studs though the earlobes as well. That is why they can stretch.I really like mine. they are teak wood inside of silver rings
