Patterns of engrailed and fushi tarazu transcripts reveal novel intermediate stages in Drosophila segmentation.
Transcripts of the engrailed and fushi tarazu genes in young Drosophila embryos are initially patterned in intervals larger than a single segment. The segmental pattern evolves in a stepwise sequence through successively smaller spatial units.
