Some scientists have reported that this trait is due to a single gene for
which unattached earlobes is dominant and an attached earlobe is
recessive. Other scientists have reported that this trait is probably due to
several genes.

This trait is reportedly due to a single gene; strait thumb is dominant and hitchhiker's thumb is
recessive.

Tongue Tongue RollingRolling

Tongue rolling ability may be due to a single gene
with the ability to roll the tongue a dominant trait and the lack of tongue
rolling ability a recessive trait.However, many twins do not share the trait, so it
may not be inherited.

Dimples are reportedly due to a single gene with dimples dominant (people
may exibit a dimple on only one side of the face) and a lack of dimples is
recessive.

Some scientists have reported that handedness
is due to a single gene with right handedness
dominant and left handedness recessive.
However, other scientists have reported that the
interaction of two genes is responsible for this trait.

This trait is reportedly due to a single gene’ the
presence of freckles is dominant, the absence of
freckles is recessive.

Hair curlHair curl

Early geneticists reported that curly hair was
dominant and strait hair was recessive. More
recent scientists believe that more than one gene
may be involved.

While allergic reactions are induced by things a person
comes in contact with, such as dust, particular foods, and
pollen, the tendency to have allergies is inherited. If a
parent has allergies, there is a one in four (25%) chance that
their child will also have allergy problems. The risk
increases if both parents have allergies.

Some scientists report that there may be a genetic component to this trait
while others have found no evidence to support this.

Colorblindness is due to a recessive allele located on the X chromosome. Women have two X chromosomes, one of which usually carries the allele for
normal color vision. Therefore, few women are colorblind. Men
only have one X chromosome, so if they carry the allele for
colorblindness, they will exhibit this trait. Thus, colorblindness is
seen more frequently in men than in women.
