The segment of chromosome of bacteria Hfr on which bears the high frequency of recombination is a segment oriented O---R, the order of transmission of characteristics being a function of their distance from the unknown origin O. The probability, for a given characteristic, of appearing among the recombinants is much weaker, the farther removed it is from origin O. There can be genetic recombination when only a small fragment of chromosome of parent Hfr is transmitted to an F- bacteria, which corresponds to the conception of Hayes 1. As to the mechanism of integration of genetic material transmitted, recombination with E. coli K 12 seems therefore that it could be aligned with transduction.
