Genomic incompatibilities in the diploid and tetraploid offspring of the goldfish × common carp cross.
Polyploidy is much rarer in animals than in plants but it is not known why. The outcome of combining two genomes in vertebrates remains unpredictable, especially because polyploidization seldom shows positive effects and more often results in lethal consequences because viable gametes fail to form during meiosis. Fortunately, the goldfish (maternal) × common carp (paternal) hybrids have reprodu...
متن کاملInduction of triploidy in grass carp Ctenopharyngodon idella Valenciennes, 1844: Comparison of cold & heat shocks
Triploidy in grass carp, Ctenopharyngodon idella Valenciennes, 1844, was induced on fertilized eggs to compare cold and heat shocks. Two simplified methods explained for verification of triploidy in grass carp. The cold shock (7 ?C) was given in three treatments for 30 min starting 2.0, 2.5 and 4.0 min after fertilization. In cold shock, the start point (2.0 min after fertilization) showed th...
متن کاملAppeared in ECAI-96 workshop: Cross-fertilisation in Planning Recovering from Failure in Temporal Planning
This paper describes an open problem in temporal planning, namely the problem of recovering from failure in collapsing time intervals. We illustrate this problem in the context of the parcPLAN planning system and show its full complexity by combining the problem with resource reasoning. We also summarise some of the progress made to tackle this problem.
متن کاملBack to Reality: Crossing the Reality Gap in Evolutionary Robotics
In this work a new method to evolutionary robotics is proposed, it combines into a single framework, learning from reality and simulations. An illusory sub-system is incorporated as an integral part of an autonomous system. The adaptation of the illusory system results from minimizing differences of robot behavior evaluations in reality and in simulations. Behavior guides the illusory adaptatio...
متن کاملthe role of russia in transmission of energy from central asia and caucuses to european union
پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
