EARLOBE ATTACHMENT

 

EARLOBE ATTACHMENT

An Earlobe is made up of connective tissues combined with a mixture of areola tissues and fat cells. Earlobes have a good blood supply, which helps in keeping them warm and maintaining balance. There are two primary types of earlobes found in humans, which include free earlobes and attached earlobes.

Free earlobes

·      Free earlobes are the most common form of ear lobes in humans. This type of earlobe is often large and hangs below the point of attachment to the head.

·      This happens due to the influence of a dominant allele. If the parents' genes express the dominant allele, the child will be born with free earlobes.

·      The free earlobe parents can also give birth to an attached earlobe child, depending on the allele gene's reaction. If parents with free earlobes give birth to a baby with attached earlobes, both of them had both a copy of the dominant and recessive allele. 

    Attached earlobes

·      Attached earlobes are not rare but are also not commonly found. Earlobes of such type are small in size and are attached directly to the side of the head.

·      This kind of lobe's structural formation is due to the absence of the dominant allele in the chromosomes. The recessive allele is expressed to form an attached earlobe. Parents with attached earlobes will not necessarily give birth only to children with attached earlobes. If the dominant allele fails to show its presence, the recessive allele will be expressed.
