  In this paper, we move from a "proof of concept" to challenging predictions
in a flavour model emerging from a single fermion family in six dimensions
(6-D) with the two extra dimensions compactified on a sphere. The most striking
predictions (beyond the basic ingredients already demonstrated for a realistic
quark mass pattern) are for the neutrino sector. Not only can 4-D Majorana
masses be generated from 6-D (where no Majorana spinors exist), but Majorana
masses are naturally associated to large mixing. The model favours inverted
hierarchy and a quasi-Dirac partial suppression of neutrinoless double beta
decay.
