Sexual reproduction is modeled and investigated in the formal framework of John von Neumann's theory of self-reproducing cellular automata. It is argued that the transition from asexual to sexual reproduction necessitates a change in number and structure of the genetic tapes involved. To an asexua...

The Impact of Single- and Double-Strand DNA Breaks in Human Spermatozoa on Assisted Reproduction Several cellular insults can result in sperm DNA fragmentation either on one or both DNA strands. Oxidative damage, premature interruption of the apoptotic... A Agarwal,C Barbroie,R Ambar,... - 《...
Considering the unique phylogenical position of cellular slime molds, analysis of sexual development in these organisms should contribute to the understanding of the mechanism and evolution of sexual reproduction systems. 展开 关键词: carbohydrates, cells, Dictyostelium, sexual development, antigens, ...
The conclusion is drawn that although the capacity for universal construction is a sufficient condition for self-reproduction, it i... CG Langton - 《Physica D Nonlinear Phenomena》 被引量: 965发表: 1984年 Explaining the geographic distributions of sexual and asexual populations Examination of the ...
Sexual attractiveness of immune-challenged male mealworm beetles suggests terminal investment in reproduction males' immunocompetence. We tested whether the activation of a male's immune system has an effect on the female's mate choice in Tenebrio molitor. We... I Kivleniece,I Krams,Janlna Dauks...

Frequent sexual reproduction and high intraspecific variation in Salix arctica: Implications for a terrestrial feedback to climate change in the High Arctic [1]聽Genetic variation at molecular loci may underlie important variation in the phenotypes of arctic plants. Such intraspecific variation may be ...
