Linkage modification with mixed random mating and selfing: a numerical study.
Although recombination cannot increase under conditions of random mating or complete selfing in regimes of constant selection, with mixed random mating and selfing, selection for increased recombination can occur. For some fitness regimes there may be selection for reduced recombination with both low and high degrees of selfing but selection for increased recombination with moderate degrees of ...
متن کاملPopulation genetics of autopolyploids under a mixed mating model and the estimation of selfing rate.
Nowadays, the population genetics analysis of autopolyploid species faces many difficulties due to (i) limited development of population genetics tools under polysomic inheritance, (ii) difficulties to assess allelic dosage when genotyping individuals and (iii) a form of inbreeding resulting from the mechanism of 'double reduction'. Consequently, few data analysis computer programs are applicab...
متن کاملReproductive system of a mixed-mating plant responds to climate perturbation by increased selfing.
How plants respond to climatic perturbations, which are forecasted to increase in frequency and intensity, is difficult to predict because of the buffering effects of plasticity. Compensatory adjustments may maintain fecundity and recruitment, or delay negative changes that are inevitable but not immediately evident. We imposed a climate perturbation of warming and drought on a mixed-mating per...
متن کاملEvolution of Mating Systems: Outcrossing versus Selfing
Mating systems vary enormously among groups of organisms. This has led to diverse definitions and approaches for investigating their evolution and maintenance. Animal mating systems are characterized by different patterns of parental investment in offspring and variation in the extent to which sexual selection shapes male and female traits (see chapter VII.4). A primary focus of most studies is...
متن کاملHitchhiking: a comparison of linkage and partial selfing.
Genetic hitchhiking occurs when alleles at unselected loci are changed in frequency because of an association with alleles at a selected locus. This association may be mediated either by linkage or partial selfing (inbreeding) and can affect the gene frequency and gametic disequilibrium at the neutral loci. Hitchhiking from partial selfing (unlinked loci) occurs more quickly than linkage hitchh...
