Answer 1

In typical relationships, one would expect the most bickering between mothers and daughters.

Answer 2

We can guess that it's going to be between the adolescent children and their parents, since on the one hand, children are negotiating their personality and autonomy and on the other hand, they are going through a lot of hormonal changes. 

In fact, the answer is "mothers and daughters " - mothers tend to have a stronger control of their daughters and this causes the daughters to rebel and to express their own personality stronger and in contrast to their mothers.
