文摘We previously defined the quasikernels for a category with terminal objects so that we could establish imitatively homological algebra for the category of all n-groups. Then confronts us a new problem: What is the structure of a quasikernel family of a morphism like? Clearly, the problem will be important for us in discussing 'exact sequences'. As to whether the terminal objects are quasinull or not, this paper will show us the existence of the union and intersection of a quasikernel family of a morphism, by giving the following four examples and two theorems.
