We present the summary of our last results on the spatial distribution and relative frequencies of Supernovae (SNe) in a large number of host galaxies from the Sloan Digital Sky Survey (SDSS). We use the locations of SNe in order to study the relations between radial/azimuthal distributions of SNe and properties of their hosts and environments. On the other hand, the vertical distribution of SNe allows to study the progenitors association to the thin or thick discs, and to the stellar halo. We also propose the underlying mechanisms shaping the number ratios of SNe types. It is important to note that there were no extended studies of the 3D distribution of SNe and structural parameters of hosts. Our study is intended to fill this gap and better constrain the nature of SN progenitors.
