The fragment size can be amplified by 295 bp through the primer, in order to prevent false positive from appearing, a pair of internal control primers C34 is designed through the invention according to a bull autosome 3 reported sequence, the fragment size is amplified by 208bp, dual PCR amplification is performed to single bull sperm through the two pairs of primers, and then the final evaluation is performed to the sperm separation purity according to the statistical analysis to the detection result.

本发明提供了一种检测X、Y精子分离纯度的引物，该引物是针对牛Y染色体上性别决定基因Sry通过PCR错配技术设计而成，通过该引物可扩增片段大小为295bp，为了防止假阳性出现，本发明根据牛3号常染色体报道序列设计了一对内标引物C34，扩增片段大小为208bp，通过上述两对引物对单个牛精子进行双重PCR扩增，然后根据对检测结果的统计分析，对分离精子纯度做出最终评价。

Spermatogenesis is a complex process of cell division and differentiation resulting in a series of molecular and morphological changes in male germ cells.

精子发生是一个多阶段，多步骤持续的细胞分裂和分化过程，它受到性染色体和常染色体上一系列基因的调控。
