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.
