A crossbreeding experiment was carried out between two local strains of Mandarah (MN) and Matrouh (MA) chicken. Thirty-four sires and 400 dams from each strain were used to produce four genetic groups. Body weights of 3067 chicks at hatch (BW0), 4 (BW4), 8 (BW8), 12 (BW12) and 16 (BW16) weeks of ...

After a decade of global diffusion, and the realisation of some economic benefits, the environmental impact of Genetically Modified (GM) crop technologies remains inconclusive and a source of considerable threat to biodiversity-rich Africa. Drawing on evidence from Ethiopia and South Africa, this...

In this study, we assessed the maternal origin of six Hungarian indigenous chicken breeds using mitochondrial DNA information. Sequences of Hungarian chickens were compared with the D-loop chicken sequences annotated in the GenBank and to nine previously described reference haplotypes representin...

The past population dynamics of four domestic and one wild species of bovine were estimated using Bayesian skyline plots, a coalescent Markov chain Monte Carlo method that does not require an assumed parametric model of demographic history. Four domestic species share a recent rapid population ex...

Two Tsigai sheep populations exist in Serbia: the Old type, called Cokan, and the New type. It is assumed that the New type results from upgrading Tsigai sheep with exotic genetic material. We investigated genetic diversity and differentiation of these types by analysing 23 autosomal microsatelli...

In this study, 30 microsatellite markers recommended by the International Society for Animal Genetics and the Food and Agriculture Organization were used to determine the extent of genetic differentiation and phylogenetic relationships among indigenous chicken populations sampled in Kenya, Uganda...

Genetic diversity of nine indigenous Chinese cashmere goat populations and one West African breed were investigated using 19 microsatellite DNA markers and fluorescence PCR. The aim was to investigate the status of the genetic resources of Chinese cashmere goats. Fourteen of the microsatellite lo...

Microarrays are an important and widely used tool. Applications include capturing genomic DNA for high-throughput sequencing in addition to the traditional monitoring of gene expression and identifying DNA copy number variations. Sequence mismatches between probe and target strands are known to a...

Rab genes encode a subgroup of small GTP-binding proteins within the ras super-family that regulate targeting and fusion of transport vesicles within the secretory and endocytic pathways. These genes are of particular interest in the protozoan phylum Apicomplexa, since a family of Rab GTPases has...
