A genetic study of the temperate coliphage λ

Abstract

1. 1. All the known markers in the temperate phage λ are linked to each other. 2. 2. Mating between pairs of intracellular particles occurs at random with respect to partner but is rather rare (average number of rounds of mating 0.5, assuming two reciprocal recombinants are formed simultaneously). 3. 3. Double crossing over in a single mating event occurs frequently in λ. 4. 4. There appears to be little or no interference between two crossovers which occur in the same mating event. 5. 5. No correlation between reciprocal recombinants in single bursts is found.
