The allele-frequency spectrum in a decoupled Moran model with mutation, drift, and directional selection, assuming small mutation rates. Theor. Popul. Biol. 81 (3), 197-209.C. Vogl, F. Clemente, The allele-frequency spectrum in a decoupled Moran model with mutation, drift, and directional ...
selection pressure from human cultivation26. Domestication signatures include altered allele frequency and a reduction in nucleotide diversity in the domestication loci. Thus, the deep elucidation of the molecular basis for natural variation in domestication traits is essential for bridging molecular analysis...
2. Understanding Directional Selection: - Directional selection occurs when one particular phenotype (a trait or characteristic of an organism) is favored over others, causing the allele frequency to shift in one direction. - Example: In the case of the peppered moth, before industrialization, lig...
Theory predicts that when populations are established by few individuals, random founder effects can facilitate rapid phenotypic divergence even in the absence of selective processes. However, empirical evidence from historically documented colonisations
Conventional wisdom in evolutionary theory considers aging as a non-selected byproduct of natural selection. Based on this, conviction aging was regarded as an inevitable phenomenon. It was also thought that in the wild organisms tend to die from diseases, predation and other accidents before they...
directional selection that rapidly increase the selected allele frequency along with longer haplotype background of the selected alleles than that of the alternative allele. (Additional file3: Figure S3). As our primary goal is to identify putative candidate genes involved in pig domestication (Figure...
Propose a mode of selection that best describes the scenario. 23. In a region without birds preying on the mice, the genotype frequency of the mice is evenly distributed. Provide an explanation for why this is most likely the case. 24. The dark fur color ...

2.1. Selection of genetic variants related to immunological Proteins/Traits We included: (i) pro-inflammatory cytokines: IL-6, tumour necrosis factor (TNF)-α, IL-12, IL-16, IL-17, IL-18; (ii) anti-inflammatory cytokines: IL-1 receptor antagonist (RA), IL-10, IL-13; (iii) chemokine...
We identified 20 regions with strong biased allele frequency across the genome, revealing signatures of selection in a rather short period. These regions harbor ample crossovers and gene conversions, which enable us to trace how selection works on the genomic fragments after meiosis. The ...
