MeSH headings : Alleles; Base Pairing; Base Sequence; Computer Simulation; Crops, Agricultural / genetics; Evolution, Molecular; Founder Effect; Gene Frequency; Genetic Variation; Genetics, Population; Genome, Plant; Likelihood Functions; Models, Genetic; Molecular Sequence Data; Oryza / genetics; Polymerase Chain Reaction; Polymorphism, Single Nucleotide; Recombination, Genetic; Selection, Genetic; Sequence Analysis, DNA

TL;DR: In a comparison of amino-acid replacements amongspecies of the mustard weed Arabidopsis with those among species of the fruitfly Drosophila, it is found that there is evidence for predominantly beneficial gene substitutions but predominantly detrimental substitutions inArabidopsis, corroborating a prediction of population genetics theory that species with a high frequency of inbreeding are less efficient in eliminating deleterious mutations.
