Fraction of galaxies that experienced at least one major (minor) merger since different redshifts, shown for BL, BD, and PS galaxies. Error bars correspond to binomial errors that are calculated using the number of galaxies and those with mergers in each bin as σ = (f_g(1 − f_g)/N_g)^0.5. For clarity, sample lines are slightly offset along the x-axis to avoid overlapping error bars. BL galaxies show the lowest major merger fraction (0.74), while BD galaxies exhibit the highest (0.91) in their lifetime.
