New COI-COII mtDNA Region Haplotypes in the Endemic Honey Bees and (Hymenoptera: Apidae) in Algeria.

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 native honey bees. To assess the genetic diversity of and , and their relationships with African and European subspecies, the COI-COII intergenic region was analyzed in 335 individuals, 68 sampled in Algeria, 71 in Europe, Madagascar, and the South West Indian Ocean archipelagos, and 196 sequences recovered from GenBank.

Allele and genotype frequencies of β-lactoglobulin gene using PCR-RFLP in Algerian local cattle populations.

Milk protein genetic polymorphisms are associated with economically important traits in dairy cattle. The objective of this study is to genotype a single nucleotide polymorphism (SNP) responsible for the amino acid changes in the beta-lactoglobulin (β-Lg) variants A and B on 85 unrelated DNA representing Algerian cattle populations: Chelifienne (28), Cheurfa (31) and Guelmoise (26). The method used is the PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism).

Natural clines and human management impact the genetic structure of Algerian honey bee populations.

Background: The Algerian honey bee population is composed of two described subspecies A. m. intermissa and A.

Maternal origin and genetic diversity of Algerian domestic chicken () from North-Western Africa based on mitochondrial DNA analysis.

Local chicken populations are a major source of food in the rural areas of Algeria. However, their origin has not been well characterized. The objectives of this study were to assess genetic diversity and maternal origin of domestic chicken from five agro-ecological regions of western Algeria: coastal (CT), inland plains (IP), highlands (HL), mountains (MT) and sahara (SH, including Oasis, Req and Erg regions).
