The expression domain of ceh-13 overlaps with that of the other Hox paralogs. A, Fluorescence images showing the expression of the C. elegans Hox genes at the two-fold embryonic stage. ceh-13 expression runs all along the anteroposterior body axis, ranging from head-to-tail. A: anterior, P: posterior. B, Expression of the C. elegans Hox genes at the L1 larval stage. Specimens transgenic for a posterior Hox paralog are shown only at the tail region (the bottom panels). A: anterior, P: posterior.
