The simplest case is after requeening. The young queens brood will all 
be of patrilines at variance with all the patrilines of the adult bees.

However, that is a rather facile answer.

With stock with varying coloured matings you do occasionally see the 
queen produce a colour change part way through her life. Its not common 
but we have seen it, a colony predominantly with yellow phase workers 
and some black shifts to predominantly dark and some yellow or vica 
versa.

Colour is the only criterion I can say I have seen it happen in, and its 
not common. I assume that this is due to poor mixing of the sperm in the 
queen, and if it happens in the way that is noticeable by colour it 
probably occasionally happens as well when the differences are not 
obvious.
