WebKeywords: gene flow / hybridization / introgression / hybrid fitness / transgene cost / crop-wild complexes INTRODUCTION Gene exchange has always been a major determinant of the evolution in crop-weed-wild complexes, i.e. groups of crops, accompanying weeds and wild species that exchange genes. On the one hand, many crops have WebMarcus R. Kronforst mainly investigates Evolutionary biology, Introgression, Monarch butterfly, Gene flow and Batesian mimicry. The concepts of his Evolutionary biology study are interwoven with issues in Phylogenetic tree, Phylogenetics, Allele, Locus and Heliconius. His studies in Locus integrate themes in fields like Papilio and Genome.
Role of genetic introgression during the evolution of cultivated …
WebIn population genetics, gene flow (also known as gene migration or geneflow and allele flow) is the transfer of genetic material from one population to another. If the rate of gene flow is high enough, then two populations will have equivalent allele frequencies and therefore can be considered a single effective population. WebFeb 26, 2024 · These analyses suggested obvious genetic introgressions from G. straminea to G. siphonantha. In addition, our coalescent-based modeling results revealed that gene … ns health iv manual
Introgression Statistics - Evolution and Genomics
WebQuantifying the size of the shared haplotype is the most straightforward test to differentiate between introgression and segregating ancestral polymorphism ((Hudson and Coyne 2009; Gao et al. 2015); see below), and thus our study provides the strongest evidence to date for introgression. However, despite gene flow between C. immitis and C ... WebJan 17, 2024 · Perhaps surprisingly, even this initial barrier to gene flow can end up laying a foundation for introgression, because niche expansion (i.e. expansion of niche breadth) can increase the chance of secondary … WebNov 10, 2024 · We show that these barriers of gene flow remain porous since many distinct species maintain some level of gene flow, similar to introgression in … night tracks
