Some models of sexual selection predict that individuals vary in their genetic quality and reveal some of this variation in their secondary sexual characteristics. Alpine whitefish (Coregonus sp.) develop breeding tubercles shortly before their spawn

International audience; In this work, we tried to optimize y-treatment of sperm to obtain large numbers of haploid gynogenetic embryos after fertilization. The analysis of increasing doses showed a typical « Hertwig effect)) in all cases, but we fou

Sporadic diploid gynogenetic fry resulted from fertilization with gamma-irradiated sperm. Their frequency increased appreciably when thermal shock treatments, beginning during the first hour of development (--0.4 degrees C lasting 6 hrs 45 min; 26-30
