AB  - The production cross sections of D<sup>0</sup> and Λ<sup>+</sup><sub>c</sub> hadrons originating from beauty-hadron decays (i.e. non-prompt) were measured for the first time at midrapidity (|y| < 0.5) by the ALICE Collaboration in proton-proton collisions at a center-of-mass energy √s=13 TeV. They are described within uncertainties by perturbative QCD calculations employing the fragmentation fractions of beauty quarks to baryons measured at forward rapidity by the LHCb Collaboration. The b―b production cross section per unit of rapidity at midrapidity, estimated from these measurements, is b. The baryon-to-meson ratios are computed to investigate the hadronization mechanism of beauty quarks. The non-prompt  production ratio has a similar trend to the one measured for the promptly produced charmed particles and to the p and  ratios, suggesting a similar baryon-formation mechanism among light, strange, charm, and beauty hadrons. The -integrated non-prompt  ratio is found to be significantly higher than the one measured in ee collisions.
