Fig. 6. Quantitative analysis of sorting patterns exhibited by wild-type and cadA^– slugs. JS24 cells (cotB::GFP; cadA⁺) and TL144 cells (cotB::GFP; cadA^–) were developed on non-nutrient agar and slugs were observed by epifluorescence microscopy at 18 hours of development. Images were separated into three different categories for JS24 cells (solid bars) and TL144 cells (stippled bars). Slugs with a clearly demarcated anterior zone were scored as sorted, while those without a clearly demarcated anterior zone were scored as non-sorted. All other aberrant patterns were scored as partially sorted.
