Cells of genotype 11eb71fd_c991_c499_a6e4_cbbe48af4041_SM1238_11 Hfr are mated with 11eb71fd_c991_c49a_a6e4_37bf4801f9cd_SM1238_11 . In the absence of any inducer in the medium, no b-galactosidase is made. However, when a 11eb71fd_c991_c49b_a6e4_957a90a32f16_SM1238_11 Hfr strain is mated with an 11eb71fd_c991_c49c_a6e4_714f4cb1d8a8_SM1238_11 under the same conditions, ?-galactosidase is synthesized for a brief period after the lac operon has been transferred. Explain this observation.
