Hanotte, Olivier H.[Chicken phenoypic and genetic diversity: Where does it come from]Chicken phenoypic and genetic diversity: Where does it come from

Domesticated in the tropical humid and sub-humid areas of Asia, the indigenous domestic chickens are now found in all agro-ecologies across the world - including temperate, cold, hot and dry environments - where they sustain the livelihood of millions of small-holder farmers. Despite this, the un...

Taye, T.Wragg, D.Mwacharo, Joram M.Hanotte, Olivier H.[Genetic disconnectedness in indigenous village chickens]Genetic disconnectedness in indigenous village chickens

Genetic diversity studies that utilize phenotypic and genetic information are informative when formulating breeding and conservation plans. The present study utilizes sequences of mitochondrial DNA (mtDNA) D-loop region of 232 village chickens from Southern and Northern Nigeria to determine the o...

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...

In their letter, Storey et al. (1) concede that there is no direct genetic support for Polynesian–South American contact. However, they claim that linguistic, archaeological, and ethnohistoric evidence supports Polynesia as the most likely source of the El Arenal-1 chickens. We disagree on two gr...

Mrode, Raphael A.Dessie, TadelleKomen, HansHanotte, Olivier H.[Long term genetic gains implementation plan]Long term genetic gains implementation plan

Oocyan or blue/green eggshell colour is an autosomal dominant trait found in native chickens (Mapuche fowl) of Chile and in some of their descendants in European and North American modern breeds. We report here the identification of an endogenous avian retroviral (EAV-HP) insertion in oocyan Mapu...

The red jungle fowl Gallus gallus is the main progenitor of domestic chicken, the commonest livestock species, outnumbering humans by an approximate ratio of six to one. The genetic control for production traits have been well studied in commercial chicken, but the selection pressures underlying ...
