Fz and Vang clones in the adult and pupal wing. fz clones in an adult wing (A, courtesy of Paul Adler, unpublished) and the pupal wing (B, courtesy of David Strutt, unpublished) and Vang clones in the adult (C, republished with permission, Genetics Society of America, Genetics.org [11] and pupal wing (D, courtesy of David Strutt, unpublished). Clone outlines are shown in black (A and C) or purple in (B and D). Arrows indicate trichome direction in B and D. Notice that the presence of the clone influences the hairs to point toward the clone in A, which is more pronounced or locally normal for the case of pre-hairs in B. The presence of the clone influences the hairs to point away from the clone in C, which is more pronounced or locally normal for the case of pre-hairs in D.
