Summary
The analysis of the progeny from three-allelic, triparental one-factor crosses in T4 showed a fraction of phages carrying allthree markers inone particle. Thesethree-allelic heterozygotes were observed in therII-region as well as in the host range gene. Their frequency (0.01–0.04% of total yield) was in the range expected from theory. This result is discussed with respect to the current picture of circular permutation in phage T4.
