There appears to be complete autonomy for the temperature sensitive mutant notched wings. Mosiac wings which have a mixture of both the wild type and the Jioncv, notched wings phenotype are shown in Figures 3, 4, 5. It is clear from these drawings that there is a longitudinal striping pattern (see, for example, 3a. 3f, 4c, 4i). Alor some mosaics, the stripes ran the entire length of the wing (4a, 4c, 5a) ; for other mosaics, the stripe ran from the middle to the distal edge (3b, 3d, 4i, 5b). A longitudinal striping pattern has been reported for wings of DrosopJiila (Bryant, 1970). For some mosaics, two distinct phenotypic areas were observed (3b, 3c) ; for others, three areas were observed. In 3a, 3e, and 3f, for example, there are two. FIGURE 3. Wings mosaic for wild type (crosshatched) and notched zvings, honey, reared at 30° C. separate honey, notched wings areas separated by a wild type area; in 4b the wild type anterior and posterior edges are separated by a honey, notched zvings region. In terms of clonal analysis, it would seem that these separate regions of the same phenotype arose from different progenitor cells in the developing wing disc. Different proportions of the two phenotypes may be present in each mosaic wing. In 4a, about ^ of the mosaic wing is wild type; in 3b about $; and, in 3f about -|. In Drosophila melanogastcr the relative sizes of mosaic patches have been used to establish the number of cells that initially were set aside for the adult wing during the first few hours of embryonic development. Perhaps in Habrobracon the rela- tive sizes of the two phenotypes give an indication of the relative proportions of the two different cell genotyp
