The distribution of regenerative potential in the wing disc of Drosophila.

The distribution of regulative potential was investigated in the wing disc of Drosophila. Ten complementary pairs of fragments were tested for their capacity to regenerate or duplicate. The distribution of positional values resulting from this data was found to be very unequal; six of the twelve clockface values were tightly clustered round the anterior--posterior compartment boundary. Despite this, complementarity between regeneration and duplication was generally maintained.
