Figure 4From: A fifth major genetic group among honeybees revealed in SyriaPrincipal component analysis (PCoA) based on 14 microsatellite loci showing patterns of genetic variation in the studied populations. (a and b) discriminate the four evolutionary lineages M, A, C and O on axes 1, 2 and 3. The studied populations cluster independently with both A and O lineages (c).Back to article page
