The stage which is most sensitive to high temperature is trachea colouring embryo(ji-3), while the stage sensitive to dry condition is body pigmentation embryo(ji-5), so these two development stages have been called high temperature sensitivity stage and dry condition sensitivity stage respectively. The gene of high temperature and dry condition sensitivity is defined as sex-linked temperature sensitivity gene, which exists in 21.5 location of Z chromosome linking closely to sch gene, and presents concealed heredity.

其中对高温最敏感的时期是气管显现期(己_3)，对干燥最敏感的时期是转青期(己_5)，这两个时期分别称为高温敏感期和干燥敏感期，高温干燥敏感性基因定义为伴性温敏基因，t与Z染色体上21.5位置的sch基因紧密连锁，呈隐性伴性遗传。
