Fig. 1. sprinter mutations yield a `lawn of denticles' phenotype in
germline clone embryos. Embryos orientated anterior left, posterior right
and ventral or ventrolateral surface facing out. (A) A typical cuticle
for wild-type embryos has a regular pattern of denticles and naked cuticle.
(B) A cuticle from srt7E4 germline clones that are
paternally rescued show minor segmentation defects and often survive to adult
stages of development. Non-paternally rescued srt7E4
germline clone embryos show a `lawn of denticles' phenotype that is typical of
loss of Wg- or Hh-signaling if the father contributes the
srt7E4 chromosome (C) or
srt
(D) from Df(3L)vin5.
