Cryptochromes (CRY) are the family of proteins proposed as the putative magnetoreceptor molecules. In birds, among others in pigeons, CRY1 is widely expressed in a retina. Homing pigeons are known for their navigational abilities, and pigeon racing is a popular sport. So, the purpose of this study was to analyze the variability of the nucleotide sequence of the homing pigeon gene, spanning the region coding the two amino acids W320 and W374 of Trp-triad, and estimate the relationship between genotypes and the racing performance. Investigations were carried out on 129 pigeons. Analysis of sequencing results indicated the to change within the seventh intron of gene. Genotypes were determined by the forced PCR-RFLP method. The influence of detected polymorphism on the results of racing pigeons in 100-400 km flights was shown. The individuals achieved significantly higher ( ≤ 0.05) mean values of ace points (AP) than the ones. Regarding the detected nucleotide change localization, the polymorphism may be involved in gene expression modulation. The to change in gene may be considered as a potential genetic marker of racing performance in homing pigeons.
隐花色素（CRY）是一类被认为是假定磁受体分子的蛋白质家族。在鸟类中，尤其是鸽子，CRY1在视网膜中广泛表达。信鸽以其导航能力而闻名，赛鸽是一项受欢迎的运动。因此，本研究的目的是分析信鸽基因核苷酸序列的变异性，该区域编码色氨酸三联体的两个氨基酸W320和W374，并估计基因型与比赛成绩之间的关系。对129只鸽子进行了调查。测序结果分析表明基因的第七内含子内发生了变化。通过强制PCR-RFLP方法确定基因型。显示了检测到的多态性对100-400公里飞行赛鸽成绩的影响。个体的平均积分（AP）均值显著高于个体（≤0.05）。关于检测到的核苷酸变化定位，多态性可能参与基因表达调控。基因中的变化可能被视为信鸽比赛成绩的潜在遗传标记。
