Abstract

Bamei pigs are special germplasm resources in Qinghai. In the specific environment of the Qinghai plateau, local breeds, through long-term natural and artificial selection, have acquired a relatively stable population structure and genetic diversity. This study revealed Bamei pigs' genetic diversity at the molecular level and the degree of introgression of commercial breeds into Bamei pigs. The mitochondrial DNA D-loop region was amplified and sequenced using the ABI 3130 DNA sequencer. Sequences were collected, edited and aligned using the MEGA 5.0, DNASTAR and ClustalX 1.81 software. Haplotypes of all sequences and genetic diversity were analyzed by DnaSP 5.0 software. We identified a total of 73 polymorphic sites in our 489 novel sequences, including 1 single variable site and 72 parsimony informative sites.Genetic diversity was analyzed in this study. The results showed that haplotype diversity, nucleotide diversity and the average number of nucleotide differences of Bamei pigs were lower than those of commercial pigs. Synthetic evaluation of genetic diversity through principal component analysis indicated that Bamei pigs also showed low genetic diversity. In summary, the results of sequence analysis showed that Bamei pigs were low in genetic diversity, and the introgression of commercial pigs into Bamei pigs was serious.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 04 July 2018.
All research outputs
#18,641,800
of 23,094,276 outputs
Outputs from Cellular & Molecular Biology Letters
#255
of 488 outputs
Outputs of similar age
#253,189
of 327,912 outputs
Outputs of similar age from Cellular & Molecular Biology Letters
#8
of 15 outputs
Altmetric has tracked 23,094,276 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 488 research outputs from this source. They receive a mean Attention Score of 2.6. This one is in the 13th percentile – i.e., 13% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 327,912 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 15 others from the same source and published within six weeks on either side of this one. This one is in the 6th percentile – i.e., 6% of its contemporaries scored the same or lower than it.
