Abstract
Thoday and Gibson1 have recently reported an experiment with Drosophila where assortative mating occurred in a small population artificially selected to remove the central portion of the distribution for number of chæta. This assortative mating was so complete that 12 generations of such selection produced two distinct lines with no overlapping.
