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.
