The allelic variations at QTL has similar molecular basis to the variations at simple Mendelian loci and the basis is that gene expressions or protein functions vary.

QTL等位基因变异与孟德尔基因变异具有类似的分子基础，即基因表达或蛋白质功能发生改变。

Conclusion the foreign gene (human Cathepsin K gene) has already integrated into mouse chromosome, and it can inherit in accordance with Mendelian inheritance.

结论外源基因(人组织蛋白酶k基因)已经整合到小鼠的染色体上，并且按孟德尔遗传定律中的分离定律进行遗传。
