Mitochondrial DNA variation in Moroccan and Spanish honey bee populations 

 -  Molecular Ecology, 4(4), p.465-471, 1995 .
<br/><br/> The mitochondrial DNAs of 192 Moroccan and 173 Spanish honey bee colonies were characterized by a rapid test involving the restriction by DruI of a PCR-fragment of the COI-COII region. In Morocco, we found eight haplotypes, all characteristic of the African (A)lineage, suggesting that most if not all the maternal lineages of the colonies repeatedly imported from Europe over the last 150 years have not contributed mitochondrial genomes to the local population. Using two new genetic distances analogous to the shared allele distance defined for nuclear genes, we showed that Morocco was most probably colonized by two sublineages, one from the north-east and the other one from the south of the country and that the contact zone between them extends dong both sides of the Atlas range. In Spain, we found eight haplotypes characteristic of lineage A (six in ommon with Morocco)md four of lineage M (the West European lineage). The distribution of haplotypes of both lineages forms a gradient with c. 1O0i'o of lineage M in the south of Spain (Seville)and up to 100
