| Research Abstract |
To date, goat genetic markers have been limited in number compared with those of other livestock. To increase the number of potentially useful goat genetics studies, we isolated microsatellite sequences from the goat genome. A total of 260 new microsatellites were successfully optimised as genetic markers. Next, we performed QTLanalysis to identify loci associated with cashmere production used developed geneticmarkers. The QTL analysis showed that markers on chromosome 5 were suggestive linked to cashmere production. Given its genomic localization and its involvement in the hair production in mammals, the IGF1 and type II keratin genes were the candidate gene for the goat cashmere production.
