Genome-Wide Analysis Reveals the Effects of Artificial Selection on Production and Meat Quality Traits in Qinchuan Cattle
Open accessAbstract
A new strain of Qinchuan cattle (QNS) has been obtained after more than forty years of selective breeding, and it shows good performance and production traits. To characterize the genetic changes that have resulted from breeding, we sequenced 10 QNS and 10 of the original breed Qinchuan cattle (QCC) for the first time, with average of 12.5-fold depth. A total of 31,242,284 and 29,612,517 SNPs were identified in the QCC and QNS genomes, 47.81% and 44.36% of which were found to be novel, respectively. Furthermore, population structure analysis revealed the selection that these cattle had experienced. Then, 332 and 571 potential selected genes were obtained, associated with enhanced immunity and acclimatization in QCC (CD5, SMARCA2, CATHL2, etc.) and production or meat quality traits in QNS (PLCD3, MB, PPARGC1A, etc.). These results revealed the efforts of selective breeding for Chinese Qinchuan cattle, and will be helpful for future cattle breeding.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
