Figure 4. Genetic diversity and demographic history of nine golden takins.
(a) The average heterozygosity of different domestic and wild animals. Genome resequencing datasets from nine golden takins were used to calculate heterozygosity as previously described (Liu et al. 2021). The heterozygosity rates of other species were reported in previous reports (Li et al. 2010, Cho et al. 2013, Dobrynin et al. 2015, Liu et al. 2021). (b) The heterozygosity and proportion of the genome in ROH from nine golden takins. (c) The distributions of ROH statistics. With the length of ROH increasing, the number of ROH gradually decreased. (d) Demographic history analysis of golden takins, Milu and snub-nosed monkeys estimated by PSMC. The gray box marks the time range of the Xixiabangma Glaciation (0.8-1.17 million years ago). “g” represents generation, “μ” represents neutral mutation rate.
