对日本鹌鹑突变体Bh进行了形态、遗传学和发育学研究。(1)新孵化的Bh型雏鸟的背部羽毛中有黑色和黄色的混合色素。在Bh型成虫羽毛中，纤毛上的黄、黑带较窄且数量较多。一些羽毛没有这些带子，呈现出介于黑色和黄色之间的中间颜色。(2)遗传分析表明，Bh性状受1对常染色体显性纯致死性基因控制，与Y(黄)、W(白)、S(银)和WE(白蛋壳)4个常染色体座位无连锁关系。(3)胚胎学研究表明，Bh基因纯合子胚胎在孵化后4-6天死亡，表现为全身出血，肝组织变性，眼睛发育不良，偶见肢体和尾巴发育不良。
Morphological, genetical and developmental studies were performed on a mutant, Black at hatch (Bh), in the Japanese quail. (1) In newly hatched Bh-type chicks, there was intermingling of black and yellow pigments in the dorsal down feathers. In the Bh-type adult feathers, yellow and black bands on the webs were narrow and large in number. Some feathers are devoid of these bands and show intermediate colouration between black and yellow. (2) Genetical analysis has shown that the Bh-character is controlled by an autosomal dominant gene with homozygous lethality and that there are no linkage between Bh-locus and the other four autosomal loci, Y (yellow), W (white), S (silver) and we (white egg-shell). (3) Embryological investigation has demonstrated that the homozygous embryos for Bh-gene die at 4-6 days of incubation, showing whole body haemorrhage, degeneration of liver tissue, less well-developed eyes and occasionally less well-developed limbs and tails.
