Contrasting population genetic structures using allozymes and the inversion polymorphism in Drosophila buzzatii
The cactophilic Drosophila buzzatii (buzzatii complex ± repleta group, Ruiz & Wasserman, 1993) is native to South America and has attained a subcosmopolitan distribution by following passively its native host plants of the genus Opuntia. Studies in natural populations have shown that second chromosome polymorphic arrangements affect life history traits and morphometric traits associated with ®t...
متن کاملThe evolutionary history of Drosophila buzzatii. XXXV. Inversion polymorphism and nucleotide variability in different regions of the second chromosome.
Inversions are portions of a chromosome where the gene order is reversed relative to a standard reference orientation. Because of reduced levels of recombination in heterokaryotypes, inversions have a potentially important effect on patterns of nucleotide variability in those genomic regions close to, or included in, the inverted fragments. Here we report sequence variation at three anonymous r...
متن کاملGeographic Patterns of Inversion Polymorphism in the Second Chromosome of the Cactophilic Drosophila buzzatii from Northeastern Argentina
The inversion polymorphisms of the cactophilic Drosophila buzzatti Patterson and Wheeler (Diptera: Drosophilidae) were studied in new areas of its distribution in Argentina. A total of thirty-eight natural populations, including 29 from previous studies, were analyzed using multiple regression analyses. The results showed that about 23% of total variation was accounted for by a multiple regress...
متن کاملGenetic Polymorphism of CYP2C19 in Pakistani Population
CYP2C19 polymorphism is associated with pretreatment drug response prediction, metabolism, and disposition. Pakistan consists of a population comprising of various ethnic groups residing in different regions of the country each claiming diverse ethnic origins. The identification of CYP450 genotypic composition of these populations is therefore necessary to avoid adverse drug reactions in these ...
