The aim of this paper is to discourse the Hardy-Weinberg (H-W) Law by investigating some selected morphological traits of participants and their relatives of Orientation programme- January 2017, Human Resource Development Centre, Pt. Ravishankar Shukla University, Raipur, India in which data have been collected by analyzing certain autosomal genetically transmitted morphological characters. As per H-W Law, Allele frequencies will remain constant over generations if there is no genetic drift, random mating, mutations, etc. having gene frequencies are p and q, the genotype frequency will be p2, 2pq, q2 respectively for the dominant, heterozygotes and recessive. In this present study total of fifteen autosomal genetically transmitted morphological characters were analyzed to see whether the distribution of morphological characters follows H-W Principles or not from 32 samples of age groups from 25 to 55 males and females. Chi square test and p values were done to have a clear view about difference in observed and expected allele frequencies. Maximum dominant characters were observed in morphological traits like handedness and eye shape which were about 29 out of 32 whereas minimum dominant characters were observed in morphological trait like dimples which was about 7 out of 32. Maximum heterozygous trait was seen in ear lobe morphological trait whereas least heterozygous were seen in morphological trait of dimples. The results showed lesser 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 no effect.

As per H-W Law, Allele frequencies will remain constant over generations if there is no genetic drift, random mating, mutations, etc. having gene frequencies are p and q, the genotype frequency will be p2, 2pq, q2 respectively for the dominant, heterozygotes and recessive. In this present study total of fifteen autosomal genetically transmitted morphological characters were analyzed to see whether the distribution of morphological characters follows H-W Principles or not from 32 samples of age groups from 25 to 55 males and females. Chi square test and p values were done to have a clear view about difference in observed and expected allele frequencies. Maximum dominant characters were observed in morphological traits like handedness and eye shape which were about 29 out of 32 whereas minimum dominant characters were observed in morphological trait like dimples which was about 7 out of 32. Maximum heterozygous trait was seen in ear lobe morphological trait whereas least heterozygous were seen in morphological trait of dimples. The results showed lesser 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 no effect.
