Influence of the galaxy mass ratio in the pair on the velocity-separation distance diagram (zoomed into a box of 200 kpc × 200 km s−1) and the probability that the pair will merge for different redshifts. Top: major merger distribution, with a mass ratio between the primary galaxy and its companion within 1:1 and 1:6. Bottom: minor merger distribution with a mass ratio in the pair lower than 1:6.
