Asymmetric introgression of African genes in honeybee populations (Apis mellifera L.) in Central Mexico.

abstract：:Identifying genetic cues of functional relevance is key to understanding the drivers of evolution and increasingly important for the conservation of biodiversity. This study introduces nuclear ribosomal DNA (nrDNA) to mitochondrial DNA (mtDNA) copy number ratios as a metric with which to screen for this functional gen...
