Based on different DNA fragments between Z and W chromosome, the developed PCR method has no risk of the mistrial of those sex identification markers depended on W chromosome, and can omit extra internal control or restriction enzyme deigestion. The DNA-based spindlin gene approach can provide a rapid, exact and low cost method for sex identification in poultry.

To investigate the methods to effectively and simply assess the CAG repeat size of HD gene which was necessary for gene diagnosis of Huntington disease, the sequence including polymorphic CAG repeat of HD gene was amplified by PCR with TaKaRa LA Taq DNA polymerase and GC buffer. PCR products were analyzed on polyacrylamide gel to distinguish normal alleles from HD alleles. The DNA fragments of affected alleles were recovered from polyacrylamide gel as templets for secondary PCR. The secondary PCR products were cloned into T vector for sequencing analysis to determine CAG repeat size. A total of 20 normal individuals and 3 members from a HD pedigree were included in this study.

Findings of the study support liang's conclusion that the probability-based tagger is more viable and less affected by the proficiency level of the learners. besides, the taggers are also examined for their ability to handle spoken features in the texts. it is revealed that pauses, repetitions and sentence fragments in learners' transcribed spoken data seriously affect the performance of the rule-based tagger.
