A test cross was conducted to analyse some linkage relationships in the chicken. Pea comb (P), naked neck (Na), tardy feathering (t), four erythrocyte alloantigen loci (Ea-C, -D, -I, -P), and the rearrangement break point (RB) of the NM 7092 t(Z;1) chromosome translocation were tested. Significant linkages were found between P and Ea-I (32.9 +/- 4.2), the RB and Ea-D (30.7 +/- 4.3), and t and Ea-D (38 +/- 4.8). The data suggest the linear order of t, Ea-D, and the RB, with t closest to the centromere. Significant linkage was also found between Na and Ea-P (32.4 +/- 4.9), confirming earlier reports.
进行了一次测交以分析鸡中的一些连锁关系。对豌豆冠（P）、裸颈（Na）、迟羽（t）、四个红细胞同种异体抗原位点（Ea-C、-D、-I、-P）以及NM 7092 t(Z;1)染色体易位的重排断点（RB）进行了检测。发现P与Ea-I之间存在显著连锁（32.9 +/- 4.2），RB与Ea-D之间存在显著连锁（30.7 +/- 4.3），t与Ea-D之间存在显著连锁（38 +/- 4.8）。数据表明t、Ea-D和RB的线性顺序，其中t最靠近着丝粒。还发现Na与Ea-P之间存在显著连锁（32.4 +/- 4.9），证实了早期报告。
