Successful invasive species can overcome or circumvent the potential genetic loss caused by an introduction bottleneck through a rapid population expansion and admixture from multiple introductions. We explore the genetic makeup and the tim...
Characterization of class I- and class II-like major histocompatibility complex loci in pedigrees of North Atlantic right whales [0.03%]
北大西洋露脊鲸谱系中I类和II类主要组织相容性复合体座位的特征分析

North Atlantic right whales have one of the lowest levels of genetic variation at minisatellite loci, microsatellite loci, and mitochondrial control region haplotypes among mammals. Here, adaptive variation at the peptide binding region of ...
Rise and fall of a hybrid zone: implications for the roles of aggression, mate choice, and secondary succession [0.03%]

Hybridization can be an important evolutionary force by generating new species and influencing evolution of parental species in multiple ways, including introgression and the consequences of hybrid vigor. Determining the ecological processe...
Adaptive functional divergence of the warm temperature acclimation-related protein (WAP65) in fishes and the ortholog hemopexin (HPX) in mammals [0.03%]

Complex interactions between topographic heterogeneity, climatic and environmental gradients, and thermal niche conservatism are commonly assumed to indicate the degree of biotic diversification in montane regions. Our aim was to investigat...
Mapping of seed shattering loci provides insights into origin of weedy rice and rice domestication [0.03%]

Tigers (Panthera tigris), like many large carnivores, are threatened by anthropogenic impacts, primarily habitat loss and poaching. Current conservation plans for tigers focus on population expansion, with the goal of doubling census size i...
Mapping genes to chicken microchromosome 16 and discovery of olfactory and scavenger receptor genes near the major histocompatibility complex [0.03%]
家鸡微染色体16的基因定位及主要组织相容性复合物附近的嗅觉和清道夫受体基因的发现

Marcia M Miller et al.
Trisomy mapping is a powerful method for assigning genes to chicken microchromosome 16 (GGA 16). The single chicken nucleolar organizer region (NOR), the 2 major histocompatibility complex regions (MHC-Y and MHC-B), and CD1 genes were all p...
Resequencing data indicate a modest effect of domestication on diversity in barley: a cultigen with multiple origins [0.03%]
重测序数据表明驯化对大麦多样性的影响较小：一个多起源栽培种的例子
