Assessment of homozygosity and fertility in meiotic gynogens of the European sea bass (Dicentrarchus labrax L.)

Second generation meiogynogens were obtained by chromosome set manipulation from meiogynogenetic females and found to be morphologically normal at 3 years of age. Interestingly, under our culture conditions, the percentage of meiogynogenetic males in the second generation was 7% as opposed to 39% in the first generation.
