Fig. 2: Horse demographic trajectory and inbreeding profiles.
From: Widespread horse-based mobility arose around 2200 bce in Eurasia
a, GONE26 demographic reconstruction based on 24 early DOM2 horse genomes; the thicker line depicts the most likely effective population size up to 200 generations preceding about 1864 bce, and the thinner lines are 500 bootstrap pseudo-replicates. Conversions to calendar years bce assume either average generation times of 8 (7–12) years or our refined estimate for the time periods considered. b, Same as a but for a set of 28 Botai horse genomes. c, Total fraction of the genome encompassing ROHs of various sizes, in which each dot represents a horse genome. For example, the category [1, 2) cM indicates the fraction of a genome within ROHs that are longer than or equal to 1 cM, but shorter than 2 cM.
