Hybrid Vigour? Genes, Genomics, and History
Is the gene 'special' for historians? What effects, if any, has the notion of the 'gene' had on our understanding of history? Certainly, there is a widespread public and professional perception that genetics and history are or should be in dialogue with each other in some way. But historians and geneticists view history and genetics very differently - and assume very different relationships bet...
متن کاملHybrid vigour and maternal environment in mice
A combination of ovarian grafting and fostering was used to study the effects of preand postnatal maternal factors on adult behaviour. Inbred mice (BALB/c and C57BL/6) and F1 hybrids were compared to assess differential sensitivity to early maternal effects. In addition to the peculiar behavioural profile of BALB mice, results revealed the existence of a cognitive process in mice and confirmed ...
متن کاملSmall RNAs as important regulators for the hybrid vigour of super-hybrid rice
Heterosis is an important biological phenomenon; however, the role of small RNA (sRNA) in heterosis of hybrid rice remains poorly described. Here, we performed sRNA profiling of F1 super-hybrid rice LYP9 and its parents using high-throughput sequencing technology, and identified 355 distinct mature microRNAs and trans-acting small interfering RNAs, 69 of which were differentially expressed sRNA...
متن کاملA Hybrid Petri Net for Modelling Hybrid Biochemical Interactions
Recently hybrid modelling and simulation of biochemical systems have attracted increasing interest. This is motivated by the need of simulating systems which integrate different sub-cellular models, and the fact that bio networks themselves are inherently stochastic, however stochastic simulation is time expensive. Compared to other methods of biological modelling, Petri nets are characterized ...
متن کاملStochastic hybrid systems for studying biochemical processes.
Many protein and mRNA species occur at low molecular counts within cells, and hence are subject to large stochastic fluctuations in copy numbers over time. Development of computationally tractable frameworks for modelling stochastic fluctuations in population counts is essential to understand how noise at the cellular level affects biological function and phenotype. We show that stochastic hybr...
