Linkage relationships of blood group P (Ea-P), naked neck (Na), silkie feathering (h), and recessive white plumage (c) were studied to attempt to clarify the h-Na-Ea-P region of linkage group III of the chicken. The Na-Ea-P linkage values obtained in this test agreed with previous reports, and pooled data were used to recalculate a map distance of 27.9 +/- 2.3 map units between these two loci. A significant chi square for linkage was calculated between Na and c; however, because of the relatively low numbers of progeny tested, the high linkage value calculated, and the absence of detectable linkage between c and the other marker genes, this was probably a chance deviation. All other linkage relationships appeared negative, supporting the current suggested linear order of these loci as h-Na-Ea-P with c not being in this chromosomal region.
研究了血型P（Ea-P）、裸颈（Na）、丝羽（h）和隐性白羽（c）的连锁关系，以试图阐明鸡的连锁群III的h-Na-Ea-P区域。本次试验获得的Na-Ea-P连锁值与先前报告一致，并使用合并数据重新计算这两个基因座之间的图距为27.9±2.3个图距单位。计算出Na和c之间存在显著的连锁卡方值；然而，由于测试的后代数量相对较少、计算出的连锁值较高以及c与其他标记基因之间未检测到连锁关系，这可能是偶然偏差。所有其他连锁关系均呈阴性，支持目前这些基因座的建议线性顺序为h-Na-Ea-P，而c不在该染色体区域。
