Abstract

SUMMARY: Further recombination data have been obtained from matings involving different F auxotrophic mutants of strain K-12 with the same K-12 F auxotroph. Variations in the distribution of sugar fermentation markers among the progeny have been explained by the influence of the ‘contra-selected’ F auxotrophic marker. It is suggested that the data supports the conception of a single linear chromosome in K-12, which fragments randomly during recombination.
