An Hfr strain that is met + pro + bio + his + was mated with an F- strain that was met - pro - bio - his -.

An Hfr strain that is met + pro + bio + his + was mated with an F- strain that was met - pro - bio - his -. Mating was interrupted and the percentage of cells with each phenotype was determined by replica plating the cells on minimal media plates that lacked met, pro, bio or his. The data shown in Figure 1 were obtained. (Figure 1)

Using the data in Figure 1, label each line on the results graph below.

Drag the phenotype to the appropriate line on the graph.

Expert Solution

The given data corresponds to the percentage of cells showing a phenotype after different time intervals upon mating of two strains. to know which curve correspond to which phenotype; simple draw a perpendicular line from the given time points 10min, 12min, 15min, 20min (dashed red line from X-axis) and draw another perpendicular line from the intersection point of the previous perpendicular on each curve. label the values at each intersection and compare them with the values given in tables.
