Haplotype provides significant insights into understanding genomes at both individual and population levels. However, research on many non-model organisms is still based on independent genetic variations due to the lack of haplotype. We conducted haplotype assembling for , a non-model organism that plays a vital role in human civilization. We described the hybrid single individual assembled haplotype of the Dezhou donkey based on the high-depth sequencing data from single-molecule real-time sequencing (×30), Illumina short-read sequencing (×211), and high-throughput chromosome conformation capture (×56). We assembled a near-complete haplotype for the high-depth sequenced Dezhou donkey individual and a phased cohort for the resequencing data of the donkey population. Here, we described the complete chromosome-scale haplotype of the Dezhou donkey with more than a 99.7% phase rate. We further phased a cohort of 156 donkeys to form a donkey haplotype dataset with more than 39 million genetic variations.
单倍型为在个体和群体水平上理解基因组提供了重要见解。然而,由于缺乏单倍型,许多非模式生物的研究仍基于独立的遗传变异。我们对一种在人类文明中起着至关重要作用的非模式生物——德州驴进行了单倍型组装。我们基于单分子实时测序(×30)、Illumina短读长测序(×211)和高通量染色体构象捕获(×56)的高深度测序数据,描述了德州驴的杂交单一个体组装单倍型。我们为高深度测序的德州驴个体组装了一个近乎完整的单倍型,并为驴群体的重测序数据构建了一个分相群体。在此,我们描述了德州驴完整的染色体规模单倍型,其分相率超过99.7%。我们进一步对156头驴进行分相,形成了一个具有超过3900万个遗传变异的驴单倍型数据集。
