10.22376/ijpbs.2019.10.1.p1-12 Volume 3 Issue 4 2012(October - December) Spatial genetic variation was assessed in the common house fly lessThan i greaterThan Musca domestica lessThan /i greaterThan . Allozymes at three gene enzyme system unraveled ten loci which revealed seventeen alleles in house fly populations. F statistics revealed that except ACPH-1 and EST-3 all the other loci show inbreeding (F lessThan sub greaterThan is lessThan /sub greaterThan greaterThan F lessThan sub greaterThan st lessThan /sub greaterThan ). Persistent heterozygosity was observed in ACPH-1(F lessThan sub greaterThan is lessThan /sub greaterThan = -0.140) which indicate random mating for this locus. M. TRIPATHI , U.R. AGRAWAL, J.
