The rearing of indigenous chickens is an integral part of the smallholder farming system in the tropics, where they are kept by the rural poor to fulfil multiple functions. Their special adaptation to environmental stresses and poor husbandry practices has made them the choice of breed for smallh...

Genome analysis reveals genetic admixture and signature of selection for productivity and environmental traits in Iraqi cattle
Most studies of infectious diseases in East African cattle have concentrated on gastro-intestinal parasites and vector-borne diseases. As a result, relatively little is known about viral diseases, except for those that are clinically symptomatic or which affect international trade such as foot an...

Variation in mitochondrial and microsatellite DNA was used to define the genetic structure of
hartebeest populations straddling a transition zone between two morphotypes (Alcelaphus
buselaphus cokei and A. b. lelwel) in Kenya. Previous analyses of mtDNA from hartebeest
populations across Africa s...

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 publication of the first draft chicken sequence assembly became available in 2004 and was updated in 2006. However, this does not constitute a definitive and complete sequence of the chicken genome, since the microchromosomes are notably under-represented. In an effort to develop maps for the...

Initially, domesticated African cattle were of taurine type. Today, we find both African Bos taurus and Bos indicus cattle, as well as their crossbreeds, on the continent of Africa and they all share the same set of African taurine mitochondrial DNA haplogroups. In this study, we report genetic v...

The chicken (Gallus gallus), like most avian species, has a very distinct karyotype consisting of many micro- and a few macrochromosomes. While it is known that recombination frequencies are much higher for micro- as compared to macrochromosomes, there is limited information on differences in lin...
