We show that a diatomic dot molecule made of two identical, verticallystacked, strained InAs/GaAs self-assembled dots exhibits an asymmetry in itssingle-particle and may-particle wavefunctions. The single-particle wavefunction is asymmetric due to the inhomogeneous strain, while the asymmetry ofthe many-particle wavefunctions is caused by the correlation inducedlocalization: the lowest singlet $^1\Sigma_g$ and triplet $^3\Sigma$ statesshow that the two electrons are each localized on different dots within themolecule, for the next singlet states $^1\Sigma_u$ both electrons are localizedon the same (bottom) dot for interdot separation $d>$ 8 nm. The singlet-tripletsplitting is found to be $\sim 0.1$ meV at inter-dot separation $d$=9 nm and aslarge as 100 meV for $d$=4 nm, orders of magnitude larger than the few meVfound in the large (50 - 100 nm) electrostatically confined dots
