Visconti-Delbrück hypothesis

Quick Reference

According to this proposal, bacteriophages multiply upon entering a host, and the replicating units so formed mate repeatedly. Mating occurs in pairs and is at random with respect to the pairing partner. During any given mating cycle, a segment of genetic material from one parent can exchange with that from a second parent phage, yielding recombinant units. See Chronology, 1953, Visconti and Delbrück.
