Abstract
Specific locus (gol-1) germ line mutations are induced by γ-rays with high frequencies (about 10-5 r-1) during cleavage divisions in zebrafish. Mutant clone sizes range from 3 to 50% of the total number of germ cells, with a mean of about 10%, when embryos are exposed between the 16 and 103 cell stages. About five pregonial cells are calculated to be present during the cleavage period.Keywords
