Why does conjugation between an Hfr strain and an F-strain not result in two Hfr strains? A) Conjugation is typically disrupted before the fertility factor can be transferred. B) The cell membranes between the two strains never fuse together. C) Hfr strains lack fertility factor. D) The transferred genes typically recombine with the recipient chromosome.

A) Conjugation is typically disrupted before the fertility factor can be transferred: During conjugation between an Hfr strain and an F- strain, the fertility factor is usually not fully transferred, so the recipient does not become an Hfr strain.
