Variations exist among human individuals as well as among groups of individuals at various levels. Study of such variations helps in revealing historical relationships among them, as also the impact of environment. Polymorphism of traits are now considered as the basis of differentiation using gene frequency data of a number of genetic loci. Among human beings inbreeding is usually uncommon because of social conventions and laws although in small isolated populations it does occur, mainly through mating between relatives. The most common type of close inbreeding is between first cousins. The effect is always an increase in frequency of genotypes that are homozygous for rare, usually, harmful recessive trait. The present investigation was planned on Meos and Sunni Muslims of Haryana because instances of close inbreeding were observed among them. P.T.C. tasting ability was studied by technique of Harris and Calamus (1949). Intercaste and bisexual differences were calculated by applying chi-square (?2) test to find out significance and distribution of these traits whereas sex differences were found to be significant both in Meos and Sunni Muslims for P.T.C. tasting ability.
