A Survey and Evaluation of Human Genetic Traits in Female Population of Chandigarh and Adjoining States of India

Abstract

Physical traits are observable characteristics determined by specific segments of DNA called genes. Genes store the information needed for the cell to assemble proteins, which eventually yield specific physical traits. Most genes have two or more variations, called alleles. An individual may inherit two identical or two different alleles from their parents. In the present study eight traits were analysed among 1000 girl students of PGGCG-11, Chandigarh. Genetic analysis has revealed that in the present study 6% population is with colourblindness,28% population has blood group O+ and B+, 92% population with Rh +ve blood group, 78% population with normal cheek , 42% population with fused earlobes, 1% population with polydactyly, 55% non-rollers, 46% with hitchhiker's thumb and 69% with straight hair. The study of human genetics trait has practical value for human welfare and also gives us a powerful tool for understanding and describing human evolution.
