Using Dermatoglyphics Pattern to Identify the Left Handed Unique Pattern and its Biological Significance-If Any

Dermatoglyphics is the scientific study of fingerprints. In humans and animals dermatoglyphics are present on fingers, palms, toes and soles. These help shed light on a critical period of embryogenesis, between four weeks and five months, when the architecture of the major organ system is developing. Left handedness is the preference for the left hand over the right for everyday activities such as writing. Studies reveal that 10% of the world population is left handed. The orientation of hand is developed in foetus and is determined by observing which hand is predominantly held close to the mouth. The gene associated with left handedness is LRRTM1 gene (leucine rich repeat transmembrane neuronal). LRRTM1 is present on chromosome 2p12 which is maternally suppressed gene that is associated paternally with handedness. It is a candidate gene for involvement in several common neurodevelopmental disorders and may have played a role in human cognitive and behavioural evolution. A study was conducted over a group of population for the identification of patterns of left handedness keeping right handed people patterns as control. In this work hundred samples were collected and were analyzed to see if any concurrent and similar patterns were present. It was observed that there were some patterns which are unique in left handed persons.
