SNP density distribution and demography reconstruction of the Hainan Partridge. a distribution of SNP density across the Hainan Partridge genome. Heterozygous SNPs between the chromosomes were annotated, and heterozygosity density was observed in non-overlapping 50-kb windows. b PSMC inference of Hainan Partridge population history based on autosomal data. The central bold lines represent inferred population sizes. The 100 thin curves surrounding each line are the PSMC estimates that were generated using 100 sequences randomly resampled from the original sequence. The mutation rate on autosomes used in time scaling, was estimated using red jungle fowl autosome data
