Any measurable or observable characteristic related to the physical attachment of the soft tissue at the base of the outer ear to the head. If an earlobe hangs free, it is referred to as "detached". If it connects directly to the side of the head, it is referred to as "attached". Earlobe attachment is a continuous trait: while most earlobes can be neatly categorised as attached or detached, some are in-between. The phenotype is EFO_0007667 (lobe attachment). Also known as: earlobe attachment.
