A preliminary search for QTLs in a cattle F2 resource populations segregating for trypanotolerance has revealed three large candidate chromosomal regions (Bta02, Bta05, Bta07). In order to narrow down the position of the trypanotolerant QTLs, we are building comparative chromosomal maps between c...

An alternative approach for the direct analysis of chromosome regions corresponding to economical traits, based on chromosome microdissection, is described. Large fragment clones isolated with primer pairs designed from chromosome fragment-specific DNA sequences were localized by fluorescence in ...

The paper first describes interleukin-12 P35 encoding gene and discusses its role. It then looks into PCR conditions and sequencing; genotyping; sequencing; polymorphism frequency; mendelian inheritance; chromosomal location in sheep and cattle of different species.

We report for the first time, and for the whole of sub-Saharan Africa, the geographical distribution and the frequency of an indicine and a taurine Y specific allele amongst African cattle breeds. A total of 984 males from 69 indigenous African populations from 22 countries were analysed at the m...

With some 180 million head. comprising more than 150 different breeds or populations of taurine Bos taurus, indicine B. indicus and intermediate origin, the African continent is home to an enormous reservoir of cattle biodiversity. Recent archaeological findings are providing new insights into th...

DNA samples from 30 Friesian, 18 N'Dama, 30 Sahiwal and 18 Barotse (derived from Bos taurus and B. indicus) cattle were amplified by the polymerase chain reaction using previously described primer sequences for amplification of the Y chromosome locus INRA124. A polymorphism with 2 alleles was det...

Trypanosomiasis is one of the most important diseases in African cattle. About 3 million cattle die every year by this disease. However, about 5 percent of the total African cattle have a natural resistance against trypanosomiasis. In a preliminary study markers linked to trypanotolerance have be...
