Question 7 cet In the long term evolution experiment, 12 replicate lines all started from the same mix of E.coli and were given the same growing conditions. There was no mixing between the replicate flasks. The cell volume was observed for the 12 replicates (different coloured lines on the graph) for the first 10,000 generations. Given these results, what can you conclude from the experiment? (more than one answer is possible)

In the long term evolution experiment, 12 replicate lines all started from the same
mix of E.coli and were given the same growing conditions. There was no mixing
between the replicate flasks. The cell volume was observed for the 12 replicates
(different coloured lines on the graph) for the first 10,000 generations. Given these
results, what can you conclude from the experiment? (more than one answer is
possible)
all lines have evolved increased cell volume
we shouldn't be surprised by the consistent results in cell volume across the
lines because all experience the same selection
| genetic drift has occurred
microevolution has occurred
|there is no variation between the lines over the different generations in cell
volume
