India; allele frequency; average heterozygosity; genetic distance; castes. ABSTRACT Alu insertion/deletion polymorphisms (Alu ACE, Alu PV92 and Alu APO) were studied in three Telugu – speaking immigrants of Tamil Nadu, to understand their affinities with Andhra Pradesh population. Gene frequencies and average heterozygosity were calculated. All the three loci are polymorphic in nature and showed high levels of heterozygosity. Phylogenetic analysis of the present data with the available data of two Tamil Nadu caste population and Yadavar of Andhra Pradesh revealed that all the three immigrant populations did not show closeness with the Andhra Yadavar
