Adult fin phenotype of several of the mutants identified in our screen. (A) Comparison of dre mutant embryo (bottom) with a wildtype sibling (top). (B) Higher magnification of the dre mutant, showing absence of the anal fin (arrow). lof/+; +/+ (C) and two lof/+;ika/ika fish (D,E), exemplifying the variablility of the ika phenotype. (F) Wild-type adult. Both long fin (H) and another long fin (G) heterozygous fish have an increased length of the fins. (I) wanda heterozyogous fish showing strong reduction of the dorsal fin, abnormal pigment pattern and abnormal body shape. (J) Severe example of stein und bein mutant fish. Both pelvic fins are absent and the dorsal fin is severely reduced. In less severe cases the dorsal fin is normal and only one of the two pelvic fins is missing. (K) finless mutant fish; all fins are missing.
