| mutations affecting pigmentation and shape of the adult zebrafish. | mutations causing a visible phenotype in the adult serve as valuable visible genetic markers in multicellular genetic model organisms such as drosophila melanogaster, caenorhabditis elegans and arabidopsis thaliana. in a large scale screen for mutations affecting early development of the zebrafish, we identified a number of mutations that are homozygous viable or semiviable. here we describe viable mutations which produce visible phenotypes in the adult fish. these predominantly affect the fins ... | 1996 | 24173565 |
