Peanuts in a shell: are they twins?

What's the genetic similarity of two peanuts sharing a shell?  I don't really know too much about plants, but wouldntheir genetic similarities be relatable to family relationships we have? If so, how close would their genetically similarity back them in the familial sense?

Each peanut is a separate set of cotyledons and the radical of an individual baby pea plant.  Each new peanut carries genes from the 'father' plant's pollen grain and from the 'mother' plants ovary.  There are multiple ovaries produced in the ovule of the pea plant (at the base of the flower).  Each peanut arises from a separate pollen grain and a separate ovary (in the case of a multi-peanut shell there are multiple ovaries per ovule).  Thus each peanut (within a multiple-peanut shell) could be thought of as being fraternal twins (not identical twins!).
