利用涉及1号染色体的5个染色体重排对蓝蛋-豌豆冠-裸颈（O-P-Na）连锁群的连锁关系进行了检测。通过将重排携带者与携带所研究性状的个体杂交来创建F1原种。然后将F1回交到隐性的、正常染色体的测试原种。对每个分离后代进行染色体和表型描述。蓝卵与豌豆冠在第1染色体短臂近1/3处存在显著连锁关系。未发现与裸颈相关。针对Z（性）染色体的2个臂测试了Barring和银，并且连锁值表明这些位点在相对臂上。Ea-H与W+、Ea-P与Na、Ea-A与Ea-E之间存在连锁关系。未观察到这些位点与1号染色体p臂上的标记重排之间的连锁。
Five chromosomal rearrangements involving chromosome 1 were utilized to test linkage relationships of the blue egg - pea comb - naked neck (O-P-Na) linkage group. An F1 stock was created by crossing rearrangement carriers with individuals carrying the traits being studied. The F1 was then backcrossed to recessive, normal chromosome tester stocks. Chromosomal and phenotypic descriptions were made for each of the segregating progeny. Significant linkage relationships were shown for blue egg and pea comb on the proximal 1/3 of the short (p) arm of chromosome 1. No linkage was found for naked neck. Barring and silver were tested against the 2 arms of the Z (sex) chromosome, and the linkage values suggest that these loci are on opposite arms. Blood group loci linkages between Ea-H and W+, Ea-P and Na, and Ea-A and Ea-E were confirmed. No linkage was observed between these loci and the marker rearrangements on the p arm of chromosome 1.
