Heterozygotes from matings of the mouse strains YBR/Cv and C3H/As have about 3 times more YBR-amylase than C3H-amylase in the saliva. The determinant for this quantitative effect is located on linkage group XVI close to or with in the structural gene for salivary amylase. The quantitative effect is the result of an increase in the rate of synthesis of YBR-amylase, and the determinant is cis acting. Studies of other mouse strains suggest that regulatory genetic elements may modulate salivary amylase production.
小鼠品系YBR/Cv和C3H/As杂交产生的杂合子，其唾液中YBR淀粉酶的含量约为C3H淀粉酶的3倍。这种数量效应的决定因素位于第十六连锁群上，靠近唾液淀粉酶的结构基因或与之相连。数量效应是YBR淀粉酶合成速率增加的结果，且该决定因素具有顺式作用。对其他小鼠品系的研究表明，调控基因元件可能会调节唾液淀粉酶的产生。
