The mutant plumage color "extended brown (EB)" of the blue-breasted quail was genetically investigated. Mating experiments revealed that the EB plumage is controlled by an autosomal, incompletely dominant allele, for which we propose the symbol The EB plumage is characterized by dark brown color, and homozygotes for this mutation generally showed darker pigmentation than the heterozygotes. DNA sequencing and PCR-RFLP analyses of the EB mutants showed a rigid association between the EB plumage and a G-to-A nucleotide substitution at position 274 in the melanocortin 1-receptor gene (), clearly indicating that is the candidate gene for the EB plumage color in the blue-breasted quail.
对蓝胸鹑的突变羽色“延伸褐色（EB）”进行了遗传学研究。交配实验表明，EB羽色由一个常染色体上的不完全显性等位基因控制，我们为此提议用符号 表示。EB羽色的特征为深褐色，该突变的纯合子通常比杂合子表现出更深的色素沉着。对EB突变体的DNA测序和PCR-RFLP分析表明，EB羽色与促黑素细胞激素1受体基因（）第274位核苷酸由G到A的替换之间存在紧密关联，清楚地表明 是蓝胸鹑EB羽色的候选基因。
