Chicken tyrp1 exons show 70 . 1 % nucleotide sequence homology with human exons . fish result shows that tyrp1 locates on the long arm of z and w near to the centromere 用荧光原位杂交进行tyrp1的染色体定位，首次将tyrp1定位在z和w染色体长臂近着丝粒的位置。

The special primers were designed and synthesized after the analysis to the nucleotide sequence homology of etrl recorded in genbank . the total rna extracted from latex was reverse - transcribed into first strain of cdna . the special amplification products ( cdna fragment ) were obtained from pcr when using the first strain of cdna as template 通过对genbank登录的已克隆的植物etr1基因序列进行核苷酸同源性分析，设计特异引物。以胶乳总rna为模板，反转录成cdna第一链，又以cdna第一链为模板进行pcr扩增，得到特异扩增片段。
