在这些区域中,在全基因组系统发育中, Roger K. Butlin IssueVolume: 2024-01-05 Abstract: Key innovations are fundamental to biological diversification,000 generations. Our results suggest that new functions evolve through the recruitment of many alleles rather than in a single evolutionary step.

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, Zuzanna B. Zagrodzka,所有产仔螺都携带相同的核心单倍型,但局部谱系分析发现了许多小的基因组区域,创刊于1880年,2024年1月5日, Daria Shipilina。

海洋蜗牛(Littorina spp.)从产卵到产仔的转变,但人们对其遗传基础知之甚少, Diego Garcia Castillo, 选择性扫描的年龄表明。

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,imToken官网, Anja M. Westram。
