Consider an experiment in which an Hfr strain of E. coli bacteria with the StrS, his+, met + alleles in its genome is mixed with an F - strain of E. coli with the StrR, his-, and met - alleles in its genome. After the cells have been cultured together for 8 hours, the mixture of cells is plated on minimal media containing Streptomycin.
1. Which genotype do you expect to be most common among the colonies that grow?
O F+: StrR, his + and met+
O F-: StrR, his - and met-
O Hfr: StrR, his + and met+
O F-: StrR, his + and met+
O F+: StrR, his - and met-
