为解决多倍体植物进化史中杂交、不完全谱系分选(ILS)和祖先种缺失导致的溯源难题，研究人员通过整合北美二倍体新测序数据，运用网状系统发育(reticulate phylogenetics)和混合分析(admixture analyses)，揭示了八倍体草莓(Fragaria)亚基因组A供体在分化前存在已灭绝/未 ...

Abstract. Species delimitation in Pinaceae is often challenged by limited morphological differentiation and introgression. In Tsuga (hemlocks), species delimitation has been most challenging among ...

Introgression has been used to generate novel allotetraploid Brassica germplasm, improving the yield of Brassica napus and expanding the genetic base of Brassica carinata. The identification of ...

Introgression in pig genome leads to their altitude adaptation Date: January 27, 2015 Source: BGI Shenzhen Summary: Research on genetic mechanism of pig altitude-adaptations underlines the ...

Introgression is a term used in genetics, particularly plant genetics, to describe the movement of a gene from one species into the gene pool of another by backcrossing an interspecific hybrid with ...

If you regularly experience headaches, dizziness, balance problems and blurred vision, our Neanderthal cousins could be to blame.

We suggest that adaptive introgression of alleles from archaic humans may be one of the central mechanisms leading to the "human revolution." The behavioral characteristics of modern humans, including ...
