Fig. 4. Demographic history and genetic load of H. hainanensis and H. reticulata.

Fig. 4

Demographic history of H. hainanensis and H. reticulata (a), genetic load metrics of H. hainanensis and H. reticulata (b, c), and box plots of frequency distribution and total lengths of homozygous fragments in different length categories in the genome of each sampled tree of H. hainanensis and H. reticulata (d). a Demographic dynamics of H. hainanensis and H. reticulata were inferred with three different values of generation time (15, 20, and 30 years) using SMC++, and the Last Glacial Period (LGP) and the Last Glacial Maximum (LGM) is highlighted in light cyan and cyan, respectively. b, c Boxplots show the accumulation of the derived deleterious mutations (DDMs) and the derived major-effect mutations (MEMs) in individuals sampled from populations of H. hainanensis and H. reticulata. Boxplots (bd) for both H. hainanensis and H. reticulata display biologically independent samples (n = 30 and 32) as data points. The center lines, box edges, and whiskers represent medians, the 25% and 75% quartiles, and the upper and lower distribution of 1.5 times of quartile range. Source data of bd are provided as a Source Data file.
