In conjugational matings between double mutants for the deo operon of Escherichia coli, haploid recombinants and extended tandem duplications deoC deoD/deoA deoB::Tn5 with the DeoC+DeoA+DeoB+DeoD- phenotype are formed (the deoD+ allele is not expressed due to the polar effect of the Tn5 insertion). Selection for the expression of the recessive deoC deoD alleles (in the thyA genome) leads to the segregation of haploid clones by duplications and also of clones that retain the diploidy but that… CONTINUE READING
