About the Cover
Three-day old zebrafish showing bilateral eye mosaicism. Genomic instability (gin) mutations, shown here in a “high-instability” background, cause this mosaicism in embryos and cancer susceptibility in adults (see MOORE et al., pp. 585–600). The whiter eye cells reflect loss of function of the wild-type allele in golden heterozygotes. (Image provided by Lindsay Rush.)
