Ancient DNA unravels the history of chickens in the Baltic Sea region and the continuity of landrace lineages [0.03%]
古代DNA揭示了波罗的海地区家鸡的历史以及地方品种系谱的连续性
Suvi Olli,Rudolf Gustavsson,Hanna Kivikero et al.
Suvi Olli et al.
Very little is known about the origins and history of domestic chickens (Gallus gallus domesticus) in northern Europe due to a lack of existing documentary and ancient DNA evidence from this region. Therefore, we conducted ancient DNA analy...
Quantitative genetics and GWAS reveal population-specific sex-ratio responses in wild European seabass (Dicentrarchus labrax) under various temperature scenarios [0.03%]
数量遗传学和GWAS揭示了野生欧洲海鲈在各种温度场景下的特定种群性别比例反应
Damien Crestel,Alain Vergnet,Emilie Delpuech et al.
Damien Crestel et al.
In populations of fish species, polygenic sex determination (PSD) can evolve in different directions, depending on environmental fluctuations and migration rates. The European seabass provides an interesting model to explore such evolutiona...

Insects are associated with diverse RNA viruses, including vertically transmitted viruses that form persistent infections without apparent symptoms. One of the first documented vertically transmitted viruses is a sigmavirus (Rhabdoviridae) ...
Alternative reproductive strategies explain asymmetries in reproductive isolation and reinforcement in two Ischnura damselfly species [0.03%]
两种豆娘鱼种中替代繁殖策略解释了生殖隔离和强化的不对称性

Jesús Ernesto Ordaz-Morales et al.
Theoretical and empirical studies of reinforcement have advanced our understanding of speciation, yet its role in polymorphic species remains understudied. Because morphs differ in behavior, morphology, and reproductive strategies, reinforc...
The relationship between genomic variation and genetic load: insights from small island populations [0.03%]
基因组变异与遗传负荷之间的关系——来自小岛种群的启示
Maëva Gabrielli,Andrea Benazzo,Roberto Biello et al.
Maëva Gabrielli et al.
Small populations face high extinction risks. This can be explained by several non-genetic and genetic factors, the latter including the loss of genetic diversity and evolutionary potential, as well as the accumulation of harmful mutations ...
Paralog-aware assembly and filtering strategies reveal minimal nucleotide variation on the macro germline-restricted chromosome of the zebra finch [0.03%]
考虑旁系同源的宏基因组装配和过滤策略揭示了斑胸草雀配子体限制染色体上的最小核苷酸变异
Augustin Chen,Francisco J Ruiz-Ruano,Orlando Contreras-López et al.
Augustin Chen et al.
The germline-restricted chromosome (GRC) of passerines is a remarkable tissue-specific chromosome that accumulated paralogs of genes from the regular "A chromosomes" over millions of years, often amplified into dozens of gene copies. In add...
Beyond the Prdm9 model: independent evolution of hybrid male sterility in house mice [0.03%]
超越Prdm9模型：小家鼠杂交雄性不育的独立进化
Pavla Klusáčková,Agata Woźniewska,Petra Dufková et al.
Pavla Klusáčková et al.
Hybrid sterility is a critical postzygotic barrier that limits gene flow during speciation, yet the genetic architecture underlying evolution of such barriers in the early stages of speciation remains poorly characterized. In house mice, F1...
Signatures of repeated genomic selection associated with human-modified landscapes in genetically independent populations of Rhinella horribilis [0.03%]
与人类改造景观相关的独立群体Rhinella horribilis的重复基因组选择痕迹

Human-modified environments constitute evolutionary scenarios where novel environmental conditions impose multiple selective pressures on wild species. Rapid adaptation to such environments is critical for species survival. Hence, decipheri...
How population subsampling to concentrate selection effects can help to find epistatic interactions of transmission ratio distortion [0.03%]

Gene-gene incompatibilities-caused by deleterious allele combinations at different loci - can impair gametophyte or zygote viability, reducing fertility or overall viability in hybrids or hybrid-derived populations. These incompatibilities ...
Structural variation in context: mechanisms, functions and selection regimes across the tree of life [0.03%]

Charikleia Karageorgiou et al.
Genomic structural variants (SVs) are central to modern genetics. However, they do not fit easily into the simple classifications and analytical frameworks that work well for single‑nucleotide polymorphisms (SNPs). The papers in this speci...
