Signatures of positive selection in African Butana and Kenana dairy zebu cattle
Butana and Kenana are two types of zebu cattle found in Sudan. They are unique amongst African indigenous zebu cattle because of their high milk production. Aiming to understand their genome structure, we genotyped 25 individuals from each breed using the Illumina BovineHD Genotyping BeadChip. Genetic structure analysis shows that both breeds have an admixed genome composed of an even proportio...
متن کاملSignatures of Selection for Environmental Adaptation and Zebu × Taurine Hybrid Fitness in East African Shorthorn Zebu
The East African Shorthorn Zebu (EASZ) cattle are ancient hybrid between Asian zebu × African taurine cattle preferred by local farmers due to their adaptability to the African environment. The genetic controls of these adaptabilities are not clearly understood yet. Here, we genotyped 92 EASZ samples from Kenya (KEASZ) with more than 770,000 SNPs and sequenced the genome of a pool of 10 KEASZ. ...
متن کاملSignatures of positive selection in East African Shorthorn Zebu: A genome-wide single nucleotide polymorphism analysis
The small East African Shorthorn Zebu (EASZ) is the main indigenous cattle across East Africa. A recent genome wide SNP analysis revealed an ancient stable African taurine x Asian zebu admixture. Here, we assess the presence of candidate signatures of positive selection in their genome, with the aim to provide qualitative insights about the corresponding selective pressures. Four hundred and tw...
متن کاملSudanese Cattle Resources and Their Productivity. a Review
Sudan possesses large population of cattle in Africa. Sudanese cattle are broadly classified into two breeds: Nilotic cattle and North Sudan Zebu cattle. Types that are related to North Sudan Zebu cattle include: Kenana, Butana (Rofaah), White Nile, Western Sudan Baggara, Foja (Dar Al-Reeh cattle), Qash cattle (Baraka cattle), Arashie cattle, Red Um Bororo, Ingessana cattle and Sudanese Fulani....
متن کاملLinkage disequilibrium and signatures of selection on chromosomes 19 and 29 in beef and dairy cattle
The objective of this study was to quantify the extent of linkage disequilibrium (LD) on bovine chromosomes 19 and 29 and to study the pattern of selection signatures in beef and dairy breeds (Angus and Holstein) of Bos taurus. The extent of LD was estimated for 370 and 186 single nucleotide polymorphism markers on BTA19 and 29 respectively using the square of the correlation coefficient (r(2))...
