Analyzing Human Traits Based on Hardy – Weinberg’s Principle
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2015, Vol 2, Issue 8
Abstract
The H-W Equilibrium states that allele frequency does not change, outside force is required to change the frequency from generation to generation. If the gene frequencies are p and q, the genotype frequency will be p2 , 2pq , q2 respectively for the dominant, the heterozygotes and the recessive in a two allele system. In this present study total 743 samples of individuals were surveyed from Jammu, India taking 16 genetically transmitted morphological characters into account to find out whether their distribution and transmission followed Hardy Weinberg’s law or not. Similarly 650 samples were analysed from Himachal Pradesh ( Rohru, Shimla, Kangra, Manali, Una ) and 516 samples were analysed from Punjab ( Ferozpur, Moga, Nawashahar, Patiala, Khanna, Ludhiana, Jalandhar, Hoshiarpur, Mansa, Bhatinda, Muktsar, Faridkot). It was observed that in region of Himachal Pradesh, India 12 characters showed higher degree of deviation than expected on application of chi square test hence, establishing that certain forces like natural selection, genetic drift, non random mating etc. have a more profound effect. It has been observed that in region of Jammu 9 characters showed higher degree of deviation than expected and in the region of Punjab 5 characters showed higher degree of deviation than expected
