Fig. 5: Admixture between IBE and DOM2 horses.
From: The genomic history of Iberian horses since the last Ice Age
a Significant D-statistics tests of the form (EA, IBE; DOM2*, X), where IBE (N = 19), X is an ancient horse (N = 16), and DOM2* define the earliest European DOM2 horses present in our genome panel (N = 8). Results are shown in red and presented as D values ± standard errors. The statistical significance was assessed following Bonferroni correction for multiple testing. b DATES36 estimates for the timeline of admixture between DOM2 and IBE. Midpoint estimates are shown in black, with confidence intervals in orange. Crossed circles indicate the radiocarbon date of the specimens analyzed, or the age inferred from archaeological context. c F4-ratio31 estimates for IBE (pink) and DOM2 (orange) genetic contributions in four successfully modelled individuals. d Geographic location of the specimens showing evidence of IBE and DOM2 admixture, with those delivering unreliable DATES36 estimates shown with smaller bold, and italicized fonts. Source data for Fig. 5a are provided as a Source Data file.
