It would be interesting to know the ploidy level.
There's also a small chance the seedling could be tetraploid.
Due to the much lower viability of triploid seed formation (when they are zygotic; this doesn't affect nucellar seed), a substantially greater proportion of the viable sexual gametes are unreduced. An unreduced 3n gamete can then combine with a normal 1n haploid, resulting in a 4n zygote.
There was one study that found a tetraploid in 1 out of 24 Oroblanco seeds.
(The much less common naturally unreduced gametes do not suffer from the triploid viability problems since they never underwent meiosis, that's why their ratio becomes higher among the viable seeds, since there are fewer viable seeds)
