Fig. 5 Phenotypes of chimeric animals. Pictures show stripes of wild-type pattern in chimeric animals produced by blastula cell transplantation of the indicated genotypes (A′, inset). The position of X0 is indicated. (A,A′) Tg(TDL358:gfp) → rse. Because GFP expression reduces with age, this animal displays weak labelling in X1V. The left boundary of the clone is marked with a white dashed line. (A) incident light, dark background, (A′) UV light. (B-D) The frequency of successful transplantations is highly variable, ranging from 10% (2/25, shd → nac;pfe; 7/41; rse → nac;pfe) to <50% (21/44 and 11/19 in transplantations of nac;pfe donors into rse and shd hosts, respectively). The size of the clones is also variable, but the quality does not depend on size, e.g. even in very small clones we observe the effect of iridophores on melanophore number.
