Abstract: We find a macroscopic manifestation of zero point quantum fluctuations in the low energy dynamics of a mixture of two species of spin-$1$ Bose gases that is absent in a single-species of spinor Bose gas. It is shown that quantum fluctuations lift an accidental degeneracy of relative orientations of two nematic directors of the two species resulting in locking of the two nematic directors. This locking effect persists in a trapping potential and a weak external magnetic field.
