Gene ph was discovered in a wild-type axolotl male received from Mexico City. Larvae homozygous for this gene become recognizable by their lighter color at hatching or shortly after. The development of their forelimbs is retarded, and all limbs are of subnormal length because of the reduction in length of their long bones. Many affected larvae die without feeding, and very few survive beyond their third month. At death, older larvae usually show abnormalities of the renal system, edema, ascites, or adhesions of the viscera. The gene is apparently a simple recessive with full penetrance.
基因ph是在一只从墨西哥城收到的野生型美西螈雄性个体中发现的。该基因纯合的幼虫在孵化时或孵化后不久就因其较浅的颜色而可被识别。它们的前肢发育迟缓，由于长骨长度缩短，所有肢体的长度都低于正常水平。许多受影响的幼虫在没有进食的情况下死亡，很少有能活过第三个月的。死亡时，较大的幼虫通常会出现肾脏系统异常、水肿、腹水或内脏粘连。该基因显然是一个完全外显的简单隐性基因。
