In the case of peppers, the ovary has many ovules in separate locules. Three in these capsicums. By the way the flower opens the most probable is that the pollen comes from the same flower, from an anther right next to the pistil ( female) that is just inside. Each grain that finally is attached to the pistil will reach an ovule and complete the fertilization. That is for each seed just one grain of pollen of the same flower most probably. Thanks for the link, I'm sure that mine aren't anywhere as hot. Somewhere in between sweet peppers and the really hot stuff.
