Reciprocal hybridization experiments were performed between the line of Beltsville Small White turkeys that has been selected for high incidence of parthenogenesis and two strains of chickens. The eggs were examined cytologically at early stages of development. In the cross of turkey females X chicken males, it was found that both male (2A-ZZ) and female (2A-ZW) zygotes are formed, but the latter are much less viable and usually die in a very early stage of development. Besides the hybrid embryos, parthenogenetic-type embryos also were found. In the cross of chicken females X turkey males, no evidence of successful hybridization was obtained. However, cell division was initiated in 100 percent of the chicken eggs. This fact suggests that turkey sperm had some enhancing effect on parthenogenetic cell division in chicken eggs.
在已经被选育出孤雌生殖高发生率的贝尔茨维尔小型白火鸡品系与两个鸡品系之间进行了 reciprocal 杂交实验。在发育早期对卵进行了细胞学检查。在火鸡雌性×鸡雄性的杂交中，发现雄性（2A-ZZ）和雌性（2A-ZW）合子都能形成，但后者的生存能力要低得多，通常在发育的非常早期就死亡。除了杂交胚胎外，还发现了孤雌生殖型胚胎。在鸡雌性×火鸡雄性的杂交中，没有获得成功杂交的证据。然而，100%的鸡蛋都开始了细胞分裂。这一事实表明，火鸡精子对鸡蛋的孤雌生殖细胞分裂有某种促进作用。 （注：“reciprocal”此处不太明确其准确意思，推测可能是“相互的”之类含义，但未找到完全对应合适中文词，暂保留英文）
