Abstract: The 7 microsatellite markers in the 11th chromosome were used to construct a linkage map of Cashmere goats with a 632 samples of 5 half-sib pedigrees after paternity testing. The results showed that the allele numbers of the 7 microsatellite markers varied from 8 to 14. The lowest and the highest values of the heterozygosity were 0.5886 and 0.9348, respectively, and the average value of it was 0.8612, indicating abundant genetic diversity in Inner Monglian Cashmere goats. Moreover, the polymorphism information content (PIC) value of 7 markers was from 0.7712 to 0.8990, and the average one was 0.8472. The length of the linkage map of the 11th chromosome was 127.7 cM. The nearest genetic distance was 5.1 cM and its location was between ILSTS049 and INRA131, however, the farest one was 41.2 cM and lay in ILSTS028 and INRA108.
