dc.description.abstractGynogenetic haploid progenies of rainbow trout, produced using UV light for sperm inactivation, were studied in comparison with normal progenies. In a total of 437 normal embryos, 3.5% of them showed chromosome abnormalities: 1.1% haploids, 1.8% triploids, and 0.4% tetraploids. In the haploid embryos, 90.6% showed NF=52 and 9.4% showed other NF (50, 51, 53, or 54); chromosome numbers for embryos with NF=52 were 28, 29, 30, and 31; two to three different chromosome numbers were observed in each progeny. Chromosome abnormalities in normal progenies seem to be a common phenomenon. Results from haploid progenies suggest that aneuploidy occurs during female meiosis.
