Ratio m = M_D/M_s as a function of the mass of dark matter M_D (top panel) and age (bottom panel) for our model galaxies. Masses are in M_⊙ and ages in Gyr. The model galaxies are in different colors and ranked according to their total baryonic mass M_B reached at the present time (black: 10⁶; blue: 10⁸; green: 10¹⁰, and red: 10¹²). In the bottom panel all the lines overlap each other.
