Phylogenetic Window Analysis for Detecting Chronological Changes in Natural Selection
Natural selection operating at the amino acid sequence level can be detected by comparing the rates of synonymous (rS) and nonsynonymous (rN) substitutions for the protein-coding nucleotide sequence, where relationships rN > rS and rN < rS conventionally indicate positive and negative selection, respectively. The direction and magnitude of natural selection operating on a protein may change dur...
متن کاملNatural selection and phylogenetic analysis.
I f Darwin were to survey the entirety of the biological sciences today, he would be pleased to observe how central phylogenies and ‘‘tree thinking’’ are to integrative research (1). Biologists of all stripes now realize that phylogenies are not exotic, but fundamental and routine tools for understanding not only history but mechanism, organization, and function of biological networks at all le...
متن کاملDetecting natural selection in genomic data.
The past fifty years have seen the development and application of numerous statistical methods to identify genomic regions that appear to be shaped by natural selection. These methods have been used to investigate the macro- and microevolution of a broad range of organisms, including humans. Here, we provide a comprehensive outline of these methods, explaining their conceptual motivations and s...
متن کاملThree-dimensional window analysis for detecting positive selection at structural regions of proteins.
Detection of natural selection operating at the amino acid sequence level is important in the study of molecular evolution. Single-site analysis and one-dimensional window analysis can be used to detect selection when the biological functions of amino acid sites are unknown. Single-site analysis is useful when selection operates more or less constantly over evolutionary time, but less so when s...

انتخاب نامساعد یکی از مشکلات اساسی در صنعت بیمه است. که ابتدا در سال 1960، توسط روتشیلد واستیگلیتز مورد بحث ومطالعه قرار گرفت ازآن موقع تاکنون بسیاری از پژوهشگران مدل های مختلفی را برای تجزیه و تحلیل تقاضا برای صنعت بیمه عمر که تماما ناشی از عدم قطعیت در این صنعت میباشد انجام داده اند .وهدف از آن پیدا کردن شرایطی است که تحت آن شرایط انتخاب یا کنار گذاشتن یک بیمه گزار به نفع و یا زیان شرکت بیمه ...
