In a very large lab population of flour beetles, body size ranges from 3 to 6 mm, with most individuals about 5 mm long. The lab population is isolated so there is no migration. Assume the body size is fully heritable and controlled by many loci.

Is it possible that, after many generations of selection, the lab population will include individuals which are 7mm long, larger than any in the original population?
