If two bacterial genes are very closely linked (less than one map unit apart), then their frequency of cotransduction will be very high, almost 100%. This is because during transduction, the phage can only package a small section of the bacterial chromosome, and if two genes are very close together, they are more likely to be packaged together in the phage particle and thus transfer together to the recipient cell.
