  Recently there is a renewed interest in exploring the Dark sector of the
universe in a more constrained way. Particularly in [1], the FIMP ( Feebly
Interacting Massive Particle) scenario was shown to be realized with a minimal
extension of the SM with three sterile neutrinos in the spirit of {\nu}MSM. In
this paper, we show that without invoking any additional symmetries of the
model, we can realize the idea of ADM (Asymmetric Dark Matter) signaling a
common origin of the matter-anti-matter asymmetries in visible as well as Dark
sectors. The model allows for a range of dark matter masses, 1 - 100keV, with
correct active neutrino masses through the Type-I seesaw mechanism. Thus, the
model explains the neutrino masses, Dark Matter abundance and replicates
matter-anti-matter asymmetry of the visible sector in the Dark sector, all in a
version of the {\nu}MSM. The asymmetry in the dark sector is manifested in the
predominance of one parity of the heavy neutrinos in the comoving frame, which
should be determinable in the ongoing experiments.
