초록

서울대공원에서 사육중인 Miniature horse 10두의 혈통정립을 목적으로 PCR에 의한 성별 판정 및 16개 microsatellite marker를 사용하여 친자감정을 실시하였다. 성별 판정에서 430 bp의 SRY band가 관찰된 7두는 숫말로 판정되었고, 친자감정에서는 멘델의 유전양식에 부합된 3두가 친자관계가 확인되었다. 향후 Miniature horse의 혈통보존 및 관리에 유용한 자료가 될 것으로 사료된다.

The aim of this study was to construct a correct pedigree of miniature horses (MH). The sex of MH was detected by PCR amplification of the sex determining region of the Y chromosome gene (SRY) prior to parentage testing. Ten random MH samples for parentage testing were genotyped by using 16 micro satellite markers. Since the SRY band (430 bp) was detected in horses No.1, 2, 6, 7, 8, 9, 10, these are male. However, the DNA segment was not identified in horses No.3, 4, and 5, which therefore are female. After genotyping, parentage testing was performed according to Mendelian fashion and International Society for Animal Genetics (ISAG) guideline. Of the 10 MH, 3 were qualified by the compatibility of 16 markers according to Mendelian fashion in the present DNA typing for parentage verification. These results can provide basic information for developing parentage verification and an individual identification system in MH.
