More than one pollen donor per hip?

Is it possible for the same rose hip to contain embryos that have been fathered by genetically different pollen donors?

As a curious aside to this topic, in the press recently it was reported that a woman gave birth to twins each of which carried a different father’s DNA (confirmed by DNA analysis).

As many as are the seeds. Each seed is from one ovule and a pollen grain so that with mixed pollen or OP each seed may have a different father all ovules being from the same mother.

Yes, this does make sense, thank you Pierre!
