Abstract Cowpea, Vigna unguiculata L. Walp., is a diploid warm‐season legume of critical
importance as both food and fodder in sub‐Saharan Africa. This species is also grown in …

The genomes of maize and other eukaryotes contain stable haplotypes in regions of low
recombination. These regions, including centromeres, long heterochromatic blocks, and …

Adaptation occurring in similar genes or genomic regions in distinct lineages provides
evolutionary biologists with a glimpse at the fundamental opportunities for and constraints to …

Crop production is becoming an increasing challenge as the global population grows and
the climate changes. Modern cultivated crop species are selected for productivity under …

Local adaptation commonly involves alleles of large effect, which experience fitness
advantages when in positive linkage disequilibrium (LD). Because segregating inversions …

Observations of genetically repeated evolution (repeatability) in complex organisms are
incongruent with the Fisher–Orr model, which implies that repeated use of the same gene …

The introduction of populations to novel environments can lead to a loss of genetic diversity
and the accumulation of deleterious mutations due to selection and demographic changes …

Studies of trait-mapping and local adaptation often identify signatures of genetically parallel
evolution, where different species evolve similar phenotypes using the same genes. Such …

Questions regarding the origin and maintenance of sexual reproduction are of abiding
interest to biologists. Both theory and empirical data suggest that homologous …
