    • Body shape variation in meiotic gynogenetic and triploid sea bass, Dicentrarchus labrax 

      Peruzzi, Stefano; Wiborg-Dahle, Stine; Haffray, Pierrick; Chatain, Beatrice; Primicerio, Raul (Journal article; Tidsskriftartikkel; Peer reviewed, 2010)
      A method of geometric morphometrics was used to characterize body shape variation in meiotic gynogenetic and triploid sea bass in comparison with diploid controls. A total of 13 coordinate landmark data were recorded on the profile of 34-month-old control (n = 81), gynogenetic (n = 117) and triploid (n = 131) siblings generated from two females (A and B). Three main axes of morphometric variation ...

    • Genetic Inactivation of European Sea Bass (Dicentrarchus labrax L.) Eggs Using UV-Irradiation: Observations and Perspectives 

      Colléter, Julie; Penman, David J; Lallement, Stephane; Fauvel, Christian; Hanebrekke, Tanja Lexau; Osvik, Renate Døving; Eilertsen, Hans Christian; D'Cotta, Helena; Chatain, Beatrice; Peruzzi, Stefano (Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
      Androgenesis is a form of uniparental reproduction leading to progenies inheriting only the paternal set of chromosomes. It has been achieved with variable success in a number of freshwater species and can be attained by artificial fertilization of genetically inactivated eggs following exposure to gamma (γ), X-ray or UV irradiation (haploid androgenesis) and by restoration of diploidy by suppression ...
