    If there were an allele for it then we would be talking about something that is the product of one gene. Earlobe attachment is not one of these things.

    I know that many genetics teachers and books claim it is, but there is copious medical research that indicates (to quote) "...simple Mendelian gene effect is unlikely to be responsible for the earlobe types." (Link to many articles below)

    So there may be descriptions of the PHENOTYPE of having attached or unattached earlobes. But the genotype is still a bit mysterious (like eye colour, also in spite of what many textbooks say).
