Mani received a recessive attached earlobe allele from his mother and a dominant free earlobe allele from his father. So he has free earlobes.
A combination of connective tissues, areola tissues, and fat cells make up an earlobe. Humans have free earlobes and attached earlobes, the two primary forms of earlobes.
Not all children born to parents with attached earlobes will also have attached earlobes. The primary chromosomal pair-derived factors that affect traits affect one's general physical appearance. When combined, some alleles have a "stronger" influence than others. The stronger allele causes the dominant qualities.Thus the trait observed is free earlobes due to the dominant allele.
