Background 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...
متن کاملGenetic variability in geographical populations of Aedes aegypti (Diptera, Culicidae) in Brazil elucidated by molecular markers
The tropical mosquito, Aedes aegypti is the most important domestic vector of urban yellow fever and dengue. Genetic population studies on this vector are important because they may lead to new tools for surveillance. An analysis of genetic structure was conducted among populations of A. aegypti from 11 localities in four demographic regions within six Brazilian federal states. Markers included...
متن کاملLimits to Adaptation in Partially Selfing Species.
In outcrossing populations, "Haldane's sieve" states that recessive beneficial alleles are less likely to fix than dominant ones, because they are less exposed to selection when rare. In contrast, selfing organisms are not subject to Haldane's sieve and are more likely to fix recessive types than outcrossers, as selfing rapidly creates homozygotes, increasing overall selection acting on mutatio...
متن کاملSelfing in genetic algebras.
The effect of self fertilization on the distribution of genetic types in a population can be represented algebraically by a linear transformation. In this paper the relationship of the transformation to the genetic algebra governing the population is investigated. In particular, the problems of multiple alleles, polyploidy and linked loci are studied.
متن کاملAnalysis of genetic variability of Fasciola hepatica populations from different geographical locations by ISSR-PCR.
Inter-simple sequence repeats markers were used to determinate the genetic variability of Fasciola hepatica populations recovered from sheep and cattle from Spain (Sp1, Sp2, Sp3 and Sp4), UK (Eng), Ireland (Ir) and Mexico (Mex). Twenty five primers were tested but only five produced 39 reproducible bands, being 71.79% polymorphic bands. This percentage ranged from 10.26% in Sp4 to 48.72% in Sp1...
