In a generalized transduction experiment,donor E.coli cells have the genotype a⁺c⁺b^-,and recipient cells have the genotype a^-c^-b⁺.Pl-mediated transductants for a⁺ were selected,and their total genotypes were determined,with the following results:
$\begin{array} { l } \text {Genotype}&\text { Number of progeny}\\\hline a ^ { + } c ^ { + } b ^ { - } &95 \\a ^ { + } c ^ { - } b ^ { - } &205\\a ^ { + } c ^ { + } b ^ { + }& 5 \\a ^ { + } c ^ { - } b ^ { + } &\underline { 195 } \\&500\end{array}$
a)What is the order of the three genes?
b)What is the cotransduction frequency for:
$a$ and $c$ ?
$a$ and $b ?$
$b$ and $c ?$
