  We consider the formation of a single spot (localized solution) in
reaction-diffusion (RD) equation on a curved manifold. Specifically, we study
the direction (alignment) of the normal to interface between maxima and minima
of concentration in the steady-state on a prolate and on an oblate ellipsoid.
We further analyse the effect of shape asymmetry on l = 1 eigenmode of the
sphere by assuming a small deformation from the spherical geometry. Our
analysis shows that the eigenfunction corresponding to highest eigenvalue align
along the symmetry axis for a prolate ellipsoid, and perpendicular to the
symmetry axis for an oblate ellipsoid. Finally, we compare the direction of
variation of the most unstable mode (eigenfunction with highest growth rate) in
the system obtained by assuming a small deformation from the sphere and the
alignment of interface normal obtain from the numerical simulations.
