Abstract

Genetic polymorphism in beef cattle (Bos indices Linn.) populations from Guimaras and (Oton Tobias Fonier, San Remigio, and Tibiao) of Panay Islands, Western Visayas, Philippines were determined using starch gel electrophoresis. From the 87 blood sera examined, nine presumptive loci were found. The populations were polymorphic for the six loci, namely: transferrin (Trf), esterasel (Este), esterase2 (Est2), esterase3 (Est3), acid phosphatase2 (Acph2) and malate dehydrogenase2 (mdh2) while monomorphic for the remaining three loci (albumin (Alb), acid phosphatasel (acphi) and malate dehydrogenasel (mdhi)). The four genotypes (CC, AB, AC and BC) of Trf locus were found to be controlled by three alleles designated as Trf", Trf° and Trf c. Meanwhile, each the three esterase loci namely: Esti, Est2 and Est3 were observed to be controlled by 2 alleles; A and B. The three esterase loci were seen to have three genotypes (AA, AB and BB). Acph2 locus contains three alleles, namely: Acph2A, Acph21 and Acph2. These control the four genotypes (AA, AB, AC, BC) observed. Mdh2 were found to have two alleles: Mdh2" and Mdfl2B. Intrapopulation variation was relatively similar to each other. It was highest among beef cattle populations from San Remigio, with an average heterozygosity (H) of 0.408. The proportion of polymorphic loci and average number of alleles per locus were seen highest in Oton beef cattle population. Interpopulation variation was lowest between populations from San Remigio and Tibiao with the highest genotypic identity value of 0.962, genetic identity value of 0.964, and lowest genetic distance of 0.252.
