The 21st century has arrived and with it the promise of genetics. Scientists predict that genetic research will lead to the eradication of many diseases and disorders. Inside the minute, twisted double-helix of our DNA lies the answer to many of our problems.

Genetics is a key factor in Personology. Take a moment to look at your hands. The pattern of veins is different on each hand! Turn your hands over and took at the wrists . . . here again, the veins have different configurations. On one wrist the veins may straddle the tendon; on the other wrist, a vein may cross the tendon.

The asymetrical aspects of the body are commonly known. Fingerprints are different on one hand from the other. Eyeglasses or contacts often require a different prescription for each eye. Some individuals have one blue eye and one brown eye.

What is the reason for this bilateral asymmetry? Genetic variation. Each of us receives 23 chromosomes from each parent. While these blend substantially, differences still appear.

In three out of four people, the right ear, right side of the face, and right side of the body, reflect the father's parentage; the left side reflects the maternal contribution. These statistics were obtained in photographic research of 44 families at the Interstate College of Personology. This college specializes in native talents and how best to express them (such as an ear for music).

Since natural talents are transmitted via the narrow genetic bridge and function through our human structure, personology research focuses on individual build and has measured thousands of adults and children. For example, hands whose fingers are nearly the same length and have square fingertips exhibit the highest hand coordination. Measurements of bilateral asymmetry can indicate which hand has the highest natural dexterity.

Because the right side of the body typically carries the father's genetic contribution, the right arm and leg generally have a more masculine posture, with the elbow standing further away from the body and the right leg slightly curved outward. Contrast this with the left side: the left elbow generally sits closer to the body and the left knee is curves inward. Interestingly, one-quarter of all subjects display a reversal of these traits.

In photographing scores of family groups, research indicates that the right side of the person, including the ear, follows the paternal heritage, together with the left forehead and left top of the head. Obviously then, the left side of the person, including the ear, follows the maternal heritage, together with the right forehead and top of head.

Bilateral variations are common and important. The highest physical coordination comes from the strongest side of the human mechanism dominating a person's action. Peak coordination arises when the dominant eye, hand and foot are on the same side of the body. The rising popularity of the Delcato-Carl treatment for stuttering and other verbal and language blocks, is largely based on redirecting "sidedness" in functioning.

Eyedness and handedness are congenital. In the natural pattern, the individual who is right-handed will also be right-eyed, with the brain's left hemisphere controlling the eyedness/handedness. The reverse is true if the individual is natively left-eyed/left-handed. Serious maladjustments of coordination, speech and thought may occur if the natural handedness is changed later in life (especially in the early school grades). This alters the natural flow of message/impulses from brain to expression and from nerve reception to brain impression. In personology such a confusion of eyedness and handedness is called mixed dominance. Mixed dominance can be an important factor in understanding the kind of expression an individual produces.

Because of bilateral asymmetry we get pneumonia first in one lung, a trick-knee on one side and a single eye that twitches when we tire. Even hair may behave better on one side than the other. This variation in structure is most probably the reason for right or left dominance and determines handedness.

Gesell of Yale postulated that native neck-torsion in infants was a key factor in determining which side is naturally the master side. Upon hearing a noise, some infants would turn left to see what made the noise, others would turn right.

The relationship between how living beings are built and how they function has a long and rich history. Aristotle, a father of science, knew the Grecian systems of his times and is said to have chosen the generals for a pupil of his, Alexander the Great. Aristotle's treatise on the subject was lost in the Dark Ages and has now been refashioned in the 21th century.
