Where do attached earlobes come from?
Attached earlobes 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.

Are attached earlobes dominant?
Autosomal Traits A single autosomal gene with two alleles determines whether you have attached earlobes or free-hanging earlobes. The allele for free-hanging earlobes (F) is dominant to the allele for attached earlobes (f). Other single-gene autosomal traits include widow's peak and hitchhiker's thumb.
