Distributions of global host galaxy properties for different SN subtypes. The top-left panel shows the relation between total mass and rest-frame g − z color, while the bottom-left panel illustrates the relation between total mass and the distance-host parameter, d_DLR. The different classifications of SNe shown in the legend include normal SNe Ia from the ZTF DR2 full sample separated by s_BV in two subgroups for normal with s_BV > 0.8 in (grey) and normal with s_BV < 0.8 in (skyblue), as well as subluminous subtypes from our sample (91bg-like, 86G-like, and 04gs-like) in (red, green and, orange). Cumulative distributions of the host galaxy parameter, d_DLR, are shown in the right side. Also, the distribution of all normal SNe in high-mass galaxies with log₁₀M_* > 10 is shown in black.
