Fig. 7. pro-1 mosaic analysis. Major embryonic lineages, somatic gonad
lineages and the SS cells are shown. Broken lines indicate six divisions
between MS and somatic gonad founders Z1 and Z4. Symbols are positioned at the
youngest cell in which the transgenic array was lost, as indicated by GFP
expression pattern (see text, and Materials and methods). Mosaic animals were
scored wild type (circle), Pro (triangle) or Emo (square). For early losses,
both gonad arms were scored. For losses within somatic gonad lineages, the
phenotype of the gonad arm in which the array was lost is indicated.
