Abstract |
The present study was carried out to investigate the blood markers of Cheju horses. The red cell types (blood groups) were tested from 73 Cheju native horses and 118 Cheju racehorses by serological procedures with 23 reagents. The blood group phenotypes observed with high frequency were Pb(34.3%), Qc(56.2%), Qb(15.1%) and genotypes Dbcm/dghm(12.3%), Dde/dghm(9.6%), Dad/bcm(6.8%), Dcgm/de(6.8%) in Cheju native horses, while Aa(63.6%), Pa(44.9%), P-(28.8%), Qabc(36.4%), Dbcm/cgm(14.4%), Dbcm/bcm(10.2%), Dbcm/de(7.6%), Dbcm/dghm(5.1%), Dde/dk(5.1%) in Cheju racehorses. Alleles observed with high frequency were Ab(0.128), Ac(0.169), Dad(0.103), Dadn(0.075), Ddghm(0.226), Pb(0.316), Qc(0.494) in Cheju native horses and Aa(0.529), Dbcm(0.306), P-(0.531), Qabc(0.197), Q-(0.504) in Cheju racehorses. No specific variation of blood groups and allele frequencies of C,K,U system were observed in Cheju native horses and Cheju racehorses. The mean heterozygosity in Cheju native horses and Cheju racehorses was observed 0.5344 and 0.5102, respectively. |
