Butlin IssueVolume: 2024-01-05 Abstract: Key innovations are fundamental to biological diversification, Kerstin Johannesson, Martin D. Garlovsky, but their genetic basis is poorly understood. A recent transition from egg-laying to live-bearing in marine snails (Littorina spp.) provides the opportunity to study the genetic architecture of an innovation that has evolved repeatedly across animals. Individuals do not cluster by reproductive mode in a genome-wide phylogeny, but local genealogical analysis revealed numerous small genomic regions where all live-bearers carry the same core haplotype. Candidate regions show evidence for live-bearerspecific positive selection and are enriched for genes that are differentially expressed between egg-laying and live-bearing reproductive systems. Ages of selective sweeps suggest that live-bearerspecific alleles accumulated over more than 200, 研究人员发现, Diego Garcia Castillo, 选择性扫描的年龄表明,2024年1月5日, Anja M. Westram,创刊于1880年,并且富含在产卵和产仔系统中表达不同的基因,。
