Unformatted text preview: E. coli determined by P1 cotransduction. The numbers given are the averages in percent for cotransduction frequencies obtained in several experiments. The values in parentheses are considered unreliable. [After J. R. Guest, Molecular and General Genetics 105, 1969, 285.] that is also arg 1 is measured. Strains transduced to both met 1 and arg 1 are called cotransductants. The greater the cotransduction frequency, the closer two genetic markers must be (the opposite of most mapping correlations). Linkage values are usually expressed as cotransduction frequencies (Figure 5-28). 44200_05_p151-184 3/4/04 10:47 AM Page 171...
