Inferring selection in partially sequenced regions.
A common approach for identifying loci influenced by positive selection involves scanning large portions of the genome for regions that are inconsistent with the neutral equilibrium model or represent outliers relative to the empirical distribution of some aspect of the data. Once identified, partial sequence is generated spanning this more localized region in order to quantify the site-frequen...
متن کاملPhylogenetical analysis of partially sequenced cytb gene of Haemoproteus columbae in pigeons and its pathological lesions in Egypt
Background: Haemoproteus columbae is widely distributed in tropical and subtropical regions, causing pseudomalaria in pigeons. Aims: The current study aimed to characterize the phylogenetic position of H. columbae in pigeons in Sharkia province, Egypt, based on partial sequencing of the cytb gene as the conserved regions. The “DNA barcode” of the cytb gene helps in designing primers that can be...
متن کاملInferring Homogeneous Regions from Rich Image Attributes
Image segmentation is an important part in any computer vision framework. However, the transition from local low-level representations to useful structures and relations in the intermediate levels has turned out to be a truly diicult problem. This paper addresses the diicult transition from low-level into intermediate-level vision, where the latter deals with producing a description of image an...
متن کاملInferring sequence regions under functional divergence in duplicate genes
MOTIVATION A number of statistical phylogenetic methods have been proposed to identify type-I functional divergence in duplicate genes by detecting heterogeneous substitution rates in phylogenetic trees. A common disadvantage of the existing methods is that autocorrelation of substitution rates along sequences is not modeled. This reduces the power of existing methods to identify regions under ...
متن کاملBackground Selection in Partially Selfing Populations.
Self-fertilizing species often present lower levels of neutral polymorphism than their outcrossing relatives. Indeed, selfing automatically increases the rate of coalescence per generation, but also enhances the effects of background selection and genetic hitchhiking by reducing the efficiency of recombination. Approximations for the effect of background selection in partially selfing populatio...
