Adult mortality rates among progeny of Leghorn X Red reciprocal crosses were observed concurrently at three North Central Region experiment stations. Female mortality rates were significantly (P less than or equal to .05) higher at all locations among progeny of the Leghorn male parent. Male mortality rates (observed at two locations) between crosses were not different and thus suggested a sex chromosome involvement with mortality rates in these crosses.
在北中部地区的三个实验站同时观察了来航鸡与红色原鸡正反交后代中的成年死亡率。在所有地点，来航鸡作为父本的后代中，雌性死亡率显著更高（P≤0.05）。两个地点观察到的杂交组合间雄性死亡率并无差异，因此表明这些杂交组合中的死亡率与性染色体有关。
