Drosophila olfactory local interneurons and projection neurons derive from a common neuroblast lineage specified by the empty spiracles gene

Table 1 Numbers of clones generated at different time-points during larval life

	Embryonic	0–4 h ALH	24 h ALH	48 h ALH	72 h ALH	96 h ALH
Nb clones	11	19	12	0	1	0

The top row summarizes the number of clones that encompass the entire progeny of a neuroblast (Nb). The numbers of uniglomerular lateral projection neurons (lPNs), multiglomerular PNs and local interneuron (LNs) labelled at different times of clone induction. ALH, after larval hatching.
