①Location of WD gene in Ch inese: Using pairwise linkage analysis and multipoint linkage analysis method, w e constructed a genetic map of DNA markers within D13q14.2-3 which refined the location of WD gene by restriction fragment length polymorphism and microsatellite polymorphism analysis;②Screen for mutations of WD gene in Chinese people: we detected the structure of 21 exons of WD ge ne in 45 patients from 39 pedigrees by PCR-SSCP(Single strand conformation poly morphism) and PCR-DNA sequencing technology, found a new mutation in exon 5 and nuclcotide sequence analysis showed it is a T insertion. We also conformed the Arg778Leu in exon 8, the highest frequence mutation point in Chinese people, wit h mutation rate 22.8%in total;③Carrier detection and presymptomatic diagnosi s of WD: Based on DNA recombination technology, we peformed successfully the gen e diagnosis in all individuals of 79 families with WD and built up a helpful spe cific enzyme cut method (PCR-Msp1) to detect the carrier and presympomatic patients in Chinese pe ople with WD.

①WD的基因定位研究：通过RFLP及微卫星多态性分析，应用两位点及多位点连锁软件，建立了中国人WD基因在D13q14.2-3区域的精细遗传连锁图谱，从而首次对中国人WD基因进行了精确定位；②WD基因突变研究：应用PCR-SSCP及DNA测序技术，对39个家系45名WD患者进行该致病基因的21个外显子突变筛选，发现WD基因5号外显子存在新的T插入突变，并证实中国人WD基因的突变热点为8号外显子，突变形式为Arg778Leu，其频率为22.8%；③WD的症状前诊断和杂合子检出：应用DNA重组技术对79个家系进行基因诊断，成功地进行了WD的症状前诊断和杂合子检出，并建立了WD的基因筛选的PCR-Msp 1酶切方法。

The genetic variations and polymorphisms of six microsatellite loci were analyzed to determine the population structure and breeding progress of BMY and Brahman cattle. The range of polymorphic information content of six loci was 0.524～0.752. The unbiased expected and observed heterozygosity were similar and were 0.7376 and 0.7396,0.6412 and 0.6537 for BMY and Brahman cattle, respectively. The expected heterozygosity was relatively high in the second generation of BMY in inter se breeding, which was congruent with the breeding progress.
