Notice that the maximum frequency of exconjugates decreased for the more distant genes. For example, about 90% of the exconjugates received the azf allele, but only about 30% received the gat allele. The lower percentage for gat is due to the fact that some conjugating cells spontaneously broke apart before they were disrupted by the blender. The probability of spontaneous disruption increases with time; so fewer cells had an opportunity to receive genes that were transferred later.
