PacBio CLR reads generated for the F1 female were partitioned by parental haplotype and assembled with Canu 1.9. Assemblies were polished with Arrow 2.3.3. Repeats were identified by RepeatMasker 4.0.9 using species-specific libraries produced with RepeatModeler 2.0.1. Annotations were generated by BRAKER 2.1.5 with Neotoma lepida RNA-seq reads and OrthoDB protein sequences. Illumina NovaSeq reads produced for the parents were assembled with CLC Genomics Workbench 12 to recover the mitochondrial genome for each species.
