aNatural selection is the gradual process by which biological traits become either more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. 自然选择是生物特征在人口在互动与他们的环境的...
根据第一段中“Natural selection is the process(过程)by which one type of animal survives because of certain characters that make it more likely to live than others. The history of the peppered moth(灰蛾)is an example of the natural selection process.(自然选择是一个过程,一种动物之所以能够...
观念1.2 核心主题:演化解释了生命的统一和多样性(CONCEPT 1.2 The Core Theme: Evolution accounts for the unity and diversity of life) 生命多样性的分类(Classifying the Diversity of Life) Charles Darwin和自然选择理论(Charles Darwin and the Theory of Natural Selection ) 生命树(The Tree of Life) 观念...
Levels of gene expression underpin organismal phenotypes1,2, but the nature of selection that acts on gene expression and its role in adaptive evolution remain unknown1,2. Here we assayed gene expression in rice (Oryza sativa)3, and used phenotypic selection analysis to estimate the type and st...
Gene ontology (GO) analyses revealed further differences in the biological processes of atrichoblasts and trichoblasts: cluster 1 (atrichoblasts) was enriched for genes involved in cell wall biosynthesis, whereas cluster 4 (trichoblasts) showed gene signatures for fatty acid metabolic process (...
For thousands of years biological phenomena were subsumed under two labels, medicine (physiology) and natural history. This was actually a remarkably perceptive division, far more penetrating than such later labels of convenience as zoology, botany, mycology, cytology, or genetics. For biology can ...
We further identified genes related to flowering time, seed germination, seed size, embryogenesis, growth, and stress responses selected during the process of cannabis domestication. The expression of flowering-related genes under long-day (LD) and short-day (SD) conditions showed that Chinese ...
2022). The selection of a suitable milling method for nanobiochar production usually depends on the purpose of the experiment and raw materials. 2.2 Ultrasonication method Ultrasonication is another effective method for producing nanobiochar. During the sonication process, a probe tip is immobilized ...
During their dispersal from Africa, our ancestors were exposed to new environments and diseases. Those who were better adapted to local conditions passed on their genes, including those conferring these benefits, with greater frequency. This process of natural selection left signatures in our genome ...
Strong purifying selection is considered a major evolutionary force behind small microbial genomes in the resource-poor photic ocean. However, very little is currently known about how the size of prokaryotic genomes evolves in the global ocean and whethe
