A type of feather structure abnormality in Japanese quail resulting from the failure of barbs to uncoil was found to be controlled by a single autosomal recessive gene, pc (porcupine). The mutation was first identified in two birds from a population homozygous for white plumage color. Porcupine quail have poor egg production, lower fertility, and higher embryonic and chick mortality compared to wildtype or heterozygotes.
在日本鹌鹑中发现一种羽毛结构异常，是由羽枝无法展开导致的，该异常由一个常染色体隐性基因pc（豪猪基因）控制。这种突变最初在一群纯合白羽色的鸟中发现的两只鸟身上被识别出来。与野生型或杂合子相比，豪猪鹌鹑产蛋量低、繁殖力低，胚胎和雏鸡死亡率高。
