Using the technique of interrupted mating, five Hfr strains were tested for the sequence in which they transmitted several different genes to an F- strain. Each Hfr strain was found to transmit its genes in a unique sequence, as follows (only the first six genes transmitted were scored). Hfr 1 F O P R S Q Hfr 2 R P O F G Y Hfr 3 Y X W Q S R Hfr 4 W Q S R P O Hfr 5 F G Y X W Q A. For each of the Hfr strains, state which donor-gene marker should be selected in the recipients after conjugation to obtain the highest proportion of recombinants that will be Hfr? Strain 1 Strain 2 Strain 3 Strain 4 Strain 5

Conjugation is defined as the method of transferring the genetic material from one bacteria to another bacteria that are placed in contact.
