We consider Λ and Λ production in a wide range of proton scattering experiments. The produced Λ and Λ may or may not contain a diquark remnant of the beam proton. The ratio of these two production mechanisms is found to be a simple universal function r = [ κ/(yp - y) ]i of the rapidity difference yp - y of the beam proton and the produced Λ or Λ, valid over four orders of magnitude, from r ≈ 0.01 to r ≈ 100, with κ= 2.86 ± 0.03 ± 0.07, and i = 4.39 ± 0.06 ± 0.15.
