Genetic Diversity And Evolution Of Disease Response Genes In Sorghum Bicolor L. Moench And Other Cereals
… of polymorphism found are consistent with both selective sweeps and balancing selection. The sorghum mlo homolog and SESPY, have old, divergent alleles, while a peroxidase and a gene with a RNA binding domain have significantly reduced diversity suggesting a recent selective sweep. Finally, we …

Comparative population genetics of the Hominoidea: An investigation of locus-specific and genome-wide influences
… Locus-specific forces of natural selection, like selective sweeps and background selection, are expected to influence only the target of selection and any sites linked to that target. In contrast, genome-wide forces are expected to influence mane different loci simultaneously. In particular, …

How Linkage Disequilibrium and Recombination Shape Genetic Variation Within and Between Species
… linked sites (background selection and/or soft sweeps) may reduce nucleotide variation even in the absence of hard selective sweeps. Second, I show that inversions are permeable to non-crossover gene conversion, which occurs throughout inverted regions in intra- and inter-specific hybrids. I …

Dissecting the evolutionary forces shaping sex chromosome evolution in papaya
… experiencing strong positive selection due to a selective sweep during human domestication. This is the first case where human domestication resulted in the evolution of a new Y chromosome with novel functions which subject it to unique evolutionary constraints. The whole genome resequencing data …

Overcoming the domestication bottleneck in soybean: mapping domestication traits and using wild soybean to improve diversity
… soja introgressions within domestication-related selective sweeps.

Illuminating the Drivers of Genomic Diversification in Lamprologine Cichlids of the Lower Congo River
… and also look for signatures of hard selective sweeps. I additionally look for signatures of concerted population bottlenecks by investigating effective population size changes in populations of <em>L. lethops</em> and its LCR congener, <em>L. tigripictilis</em>,<em> </em>from …

Population genomics and domestication of the Black Soldier Fly (Hermetia illucens L.)
… to converge in populations experiencing parallel selective pressures across the globe. After documenting genetic diversity, I performed phenotypic characterisation for several domesticated strains. This work revealed both genotype- and family-environment interactions which suggested a genetic and …
