indentations on their cheeks called dimples.
• These two images show the difference between
a regular thumb and a “Hitchhiker’s thumb.”
Because of a genetic difference, one can bend

• Tongue rolling is a
genetic trait certain
people have that
allows them to curl
their tongue.
• Some people have toes that decrease (get
smaller) in size from the big toe to the small one.
• Others have a second toe that is longer than
their big toe.
• Are you right or left thumbed? Put your hands
together, interlocking your fingers. Which thumb
is on top?

person with attached ear lobes will have the
lowest point of the ear lobe attached to the face.

• Right / left dominance is the
tendency to favor one side of
the body over the other.
People generally have a
dominant eye, meaning the
brain chooses between images
perceived by the right eye and
the left eye. If neither eye is
dominant, the image jumps
from one eye to the other.
There is no accepted
correlation between hand
dominance and eye
dominance.
Procedure
Hold an index card with a small hole in the center at arm's length.
Look through the hole with both eyes at a distant object. Close one
eye, then the other. The eye that keeps the object centered in the hole
is the dominant eye.
