How many SNPs are needed to provide an accurate estimate of lineage C introgression into black honey bees?

, 2013
Beekeeping activities, especially queen trading, have shaped the distribution of honey bees subspecies in Europe, which have resulted in extensive introductions of two lineage C subspecies, A. m. ligustica and A. m. carnica, into western Europe. As a consequence, replacement and gene flow between native and commercial populations have been occurring at

Allele Frequencies of Genetic Variants Associated with Varroa Drone Brood Resistance (DBR) in Apis mellifera Subspecies across the European Continent

Insects
Implementation of marker-assisted selection (MAS) in modern beekeeping would improve sustainability, especially in breeding programs aiming for resilience against the parasitic mite Varroa destructor.

New COI-COII mtDNA Region Haplotypes in the Endemic Honey Bees Apis mellifera intermissa and Apis mellifera sahariensis (Hymenoptera: Apidae) in Algeria

Insects
The practice of beekeeping in Algeria is of great cultural, social, and economic importance. However, the importation of non-local subspecies reported by beekeepers has disrupted the natural geographical distribution area and the genetic diversity of the

Evolutionary Origin and Genetic Diversity of the Pannonian Ecotype of Apis mellifera carnica Colonies in Hungary Based on Mitochondrial DNA and Microsatellite Markers

Biology
Honey bees are crucial to both the ecosystem and the economy. However, they are subject to different influences that can lead to a loss of genetic diversity.

A novel SNP-based tool for estimating C-lineage introgression in the dark honey bee (Apis mellifera mellifera)

, 2018
The natural distribution ofthe honeybee (Apis mellifera L.) hás been changed by humans in recent decades to such an extent that the formerly widest-spread European subspecies, Apís mellifera mellifera, is threatened by extinction through introgression from highly divergent commercial strains in large tracts of its range. Conservation efforts for A.

Large Scale Mitochondrial Evidence of C-lineage Dominance in European Honey Bees

In Europe, distribution of the several endemic honey bee (Apis mellifera) subspecies has suffered a considerable shift in the last century. In particular, beekeepers tend to favour subspecies of Eastern European ancestry (C-lineage), such as the Italian honey bee (A. m. ligustica), due to their perceived docility and high honey production. As a result,
