Earlobe also known as lobules auricular is the soft fleshy lower
part found at the base of the external ear. It is the only part of
the auricle not supported by cartilage (Richard et al. 2005). It is
composed of the tough areolar and adipose (fatty) connective
tissues lacking the firmness and elasticity of the rest of the
pinna (Chummy 1999, Keith and Arthur 2006). Earlobes
average about 2cm long and elongate slightly with age (Sharma
et al. 2007, Anadi et al. 2007). It is either directly attached to
the lateral side of head or free hanging freely away from the
lateral side of head. The free type is slightly bigger than the
attached earlobe (Azaria et al. 2003). This variation in
attachment of earlobe is a trait that is inherited from parents and
its inheritance follows a pattern. It is one of the genetic trait
may be dominant or recessive on the different people according
to the races or ethnic group.
To determine the frequency of the human genetic trait for
earlobes among Brahmin community of Madi Rambeni-4,
Difficult to collect data from whole community.
4. MATERIALS AND METHODS
Direct Observation: I had visited to the home and observed the
trait of each member of the family.
Study Area: My hometown was selected for this survey which
is located at Sankhuwa Sava district Madi
Rambeni V.D.C. ward no 4.

Fig. 2: Diagram showing the Percentage of people having
attached and free earlobes.
There were the majority of people having free earlobes
comprising 84.29 % in Brahmin community which shows that
free earlobe is dominant character over attached earlobes
which supports the view of Ordu et al. (2014) who also
concluded the free earlobes is dominant with 74.14% but
Carriere (1922), in contrast, was with opposite view showing
high proportion of people with attached earlobes.
Similarly, (Sharma et al. 2007) observed 64.9% for free
earlobes among Indian people which is almost similar to this
Furthermore, similar proportions of free earlobes among male
and female shows male and female offspring inherited the trait
from both mothers and fathers irrespective of the sex.
According to the survey, It is observed that maximum number
of Brahmin in community have free earlobes and very less have
attached earlobes in Madi Rambeni-4, Sankhuwa Sava. Hence,
the dominant character of Brahmin ethnic group is the presence
of free earlobes which is inheritable character.
