Researching on the fine‐structure and admixture of the worldwide chicken population reveal connections between populations and important events in breeding historyAdmixtureAsian breedsChickensGenomic structureSelectionHere, we have evaluated the general genomic structure and diversity, and studied the ...
(Nei's genetic distance), andpopulation genetic structure(using pair-wise FSTanalysis) of chicken populations in India. These studies revealed that the nondescript desi birds have a great genetic variation that can be leveraged to revive their genetic potential for potential usage in backyard ...
This analysis revealed evidence of parallel differentiation in genes relevant to appearance and production traits exemplified with the candidate geneOPG, implicated in Osteoporosis, a disorder related to overconsumption of calcium in egg-laying hens. Our results illustrate the potential for population ...
Thus DNA pools are effective in the preliminary assessment of genetic variation of populations and markers. Mean genetic distance indicates the extent to which a given population shares its genetic diversity with that of the whole tested gene pool and is a useful criterion for conservation of ...
aThe chicken is a domesticated fowl, a subspecies of the Red Jungle fowl. As one of the most common and widespread domestic animals, and with a population of more than 24 billion in 2003, there are more chickens in the world than any other species of bird. Humans keep chickens primarily ...
which were found as significant associated SNPs with 15 traits in a Beijing-You crossed Cobb F2 resource population by genome-wide association study analysis; (iii) 7.63 K SNPs from 861 candidate genes of economic traits; (iv) the 0.94 K SNPs related to residual feed intake; and (v...
where µ is the population mean, 1 is a vector of 1s, the independent variable Xi is a vector of expression values of the ith gene, and bi is the effect of the ith gene on the trait under study. The EN model uses a mixture of l1 and l2 penalties and can be formulated as follow...
(e.g. blood vessels, muscles, tracheas and gonads). This leads to suggest that theFmtraits could not be enterily fixed in the population. Recently of concern is the fact that, due to the no fixation ofFmtraits, changes are occurring in Ayam Cemani population on the most distinguish ...
Lesser Prairie-Chickens have experienced substantial declines in terms of population and the extent of area that they occupy. While they are an elusive species, making it difficult at times to monitor them, current evidence indicates tha... DA Haukos,C Boal - 《Crc Press》 被引量: 19发表:...
The within population variation in growth performance (body weight, BW and body weight gain, BWG), fed intake (FI) and feed conversion ratio (FCR) in the NIC was investigated using body weight lines (high and low lines) created from purebred progenies of five (5) sire families established ...
