Four Alu insertion/deletion polymorphisms (Alu PLAT, Alu ACE, Alu PV92 and Alu APO) were studied in jatt sikh population from Jammu region, J&K. Blood samples were collected from fifty unrelated healthy donors. DNA was isolated and amplified by PCR and subjected to agarose gel electrophoresis. Gene frequencies were calculated and were used to calculate heterozygosity and average heterozygosity. All the four loci are polymorphic in nature and showed high levels of heterozygosity. The average heterozygosity is recorded as 0.4608 to 0.4928. https://www.biotech-asia.org/vol7no1/alu-insertion-deletion-polymorphisms-in-jatt-sikh-population-of-jammu-jk/ ALU insertion/deletion polymorphisms; jatt sikh; allele frequency; average heterozygosity.
