Abstract

Enzyme polymorphism in giant honey bee, Apis dorsta from different elevations in Mt Makiling, Laguna was anlayzed using starch gel electrophoresis Seventeen presumptive loci were observed encoding for four enzymes: five isoloci liar acid phosphatase, five for alkaline phosphatase, six for esterase and one for malic enzyme A(7111- I, ACP14-2b, Al.PH-2b, EST-la and EST-lb showed polymorphism, while the rest were monomorphic. In terms of presumptive allelozymes in each locus. S (slow) and F (last) were observed for ACPH-1, ACPH-2b, ALPH-I, ALPH-2b, EST- la and EST-I b ACPH-3 and -4 were unique to lowland population while EST-4 for midland population. EST-3 was observed the in upland population. ALPII- I FF, ALPI l-2h FF, EST-la FF, EST-la FF, EST-lb FF were only found in the upland population Average number of alleles per locus for the different elevations was approximately one The calculated proportion of polymorphic loci indicated higher polymorphism in upland (0 294) than in lowland and midland which gave the same value (0 059). The same trend could be noted for average heterozygosity wherein upland population had the highest value (0 0243). The higher genetic polymorphism observed in the upland population might be due to prevailing environmental conditions in that area that favor increased enzyme variability
