Boy Scout – Relationship between Moroi Vampires and Dhampir Offspring

A pretty interesting plot hook has presented itself and made me curious about the relationship between Dhampir and their respective vampiric parents. I've reviewed some of the basic information given for each, but it does not talk too much about the relationship between the two.

Are there any traditions that talk about the relationships or dispositions that normally exist between these two?

More specifically, the Fullblood Moroi vampire in the direction of her half-blood offspring?
