초록

고양이의 혈통 등록을 위한 개체식별 및 친자판정을 목적으로 microsatellite DNA다형을 조사한 결과 다음과 같은 성적을 얻었다. 고양이 20두를 대상으로 microsatellite DNA다형의 대립유전자를 조사한 본 연구에서는 관찰된 대립유전자의 수는 $3{\sim}8$개 (평균 5.5개)이며 marker별 대립유전자는 FCA005 142bp (0.3750), FCA026 148 bp (0.5500), FCA075 136 bp (0.5000), FCA105 191 bp (0.4250), FCA224 156 bp (0.7750), FCA229 166 bp (0.6500), FCA240 163 bp (0.3000), FCA293 185 bp (0.5000), FCA453 186 bp (0.5500), FCA651 134 bp (0.6750) 대립유전자가 높은 빈도로 관찰되었다. Expected heterozygosity와 PIC는 각각 $0.390{\sim}0.827$(평균 0.639), $0.357{\sim}0.780$(평균 0.581)으로 나타났고 FCA240의 marker는 PIC value가 0.70 이상이었다. 또한 PE는 $0.076{\sim}0.444$으로서 10개 marker를 조합시 total PE는 0.9441로 관찰되었다. 10개의 microsatellite DNA다형 좌위를 가지고 친자관계를 분석한 결과 8두 중에서 1두(12.50%)가 모순으로 판정되었다. 또한 국내에서 사육중인 고양이의 개체식별 및 친자판정에 microsatellite marker를 활용할 수 있을 것으로 사료된다.

A total number of 20 cat samples including 8 parentage testing and 12 individual identification were genotyped. Genomic DNA was extracted from buccal swab, and genotyped by using 10 microsatellite markers (FCA005, FCA26, FCA224, FCA240, FCA453, FCA293, FCA075, FCA105, FCA229, and FCA651). This method consisted of single PCR procedure and showed reasonable amplification of all PCR products. Genotypes were determined by genetic analyzer. The number of alleles per locus of cats varied from 3 to 8 with a mean value of 5.5. Expected heterozygosity was ranged from 0.390 to 0.827 (mean 0.639) and the total exclusion probability of 10 microsatellite loci was 0.9441. Of the 10 markers, FCA240 marker has relatively high PIC value (>0.7). Of the 8 cats, 7 cats were qualified by compatibility according to the Mendelism. These results can give basic information for developing parentage verification and individual identification system in cat.
