This table shows the number of embryos used to calculate median positions for each expression boundary at each point in time (M. abdita: white rows; D. melanogaster: grey rows). Ant: anterior, Post: posterior domain. A indicates anterior, P posterior boundary of a domain. Time classification as defined in Wotton et al. (2014) for M. abdita and in Surkova et al. (2008b) for D. melanogaster: C11–13 correspond to cleavage cycles 11 to 13; T1–8 represent time classes subdividing C14A. Our M. abdita expression dataset consists of a total of 367 embryos (91 stained for hb, 83 for Kr, 87 for gt, and 106 for kni). An additional 115 embryos make up the dataset for maternal co-ordinate and terminal gap genes shown in Supplementary file 1. The D. melanogaster gap gene dataset has been published previously (Crombach et al., 2012a). It is included here for comparison.
