Fig. 2.

Relative positions of gap and Eve protein expression domains are maintained in wild-type versus tll^g embryos. Integrated (averaged) quantified expression patterns of Eve (grey/black), as well as gap gene products Gt, Hb, Hkb, Kni and Kr (coloured) are shown for wild-type and tll^g embryos at time classes t2, t4, t6 and t8. Vertical axes show fluorescence intensity in arbitrary units ranging from 0 to 255. Horizontal axes represent A–P position in percent (where 0% is the anterior pole). Only the trunk region of the embryo (35–92% A–P position) is shown. See the Materials and methods section for details on data quantification and time classification.
