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.

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.

WebPopulation genomic analyses of range-wide and broadly sympatric accessions revealed extensive gene flow between these taxa, particularly in sympatry. Despite widespread introgression, Mimulus glaucescens, emerged as monophyletic and largely comprised a single ancestry that was found at intermediate frequency within M. guttatus. WebJul 1, 2009 · However, interspecific gene flow (introgression) can affect species integrity. If some genome components were less prone to introgression than others, they should be particularly suitable to delimitate species. Recent simulation studies have predicted a negative correlation between intra- and interspecific gene flow, suggesting that markers ...
