Figure Lengend Snippet: Divergence times of multiple falcon species and populations. ( A) Bayesian chronogram (time-calibrated phylogenetic tree) of 42 falcons based on whole mitogenome (mtDNA) sequences (excluding the control region, CR) with chicken mtDNA as an outgroup, generated using Beast2. The nodes are labeled with divergence time in million years ago (MYA), based on the estimated divergence time between chicken and falcons of 88 ± 10 MYA. A full tree with confidence intervals of the age estimates can be found in Fig. S3. ( B) Maximum-likelihood phylogenetic tree using an alignment of W-specific variants (3,007 SNPs) in 39 female falcons. The tree was constructed using K2P + R2, which was the best-fit model according to BIC. Branch labels represent SH-aLRT support (%), aBayes support, and ultrafast bootstrap support (%), respectively. The red cluster denotes gyrfalcons (GF) and the green denotes Altai gyrfalcon-like falcons (GLF), the blue cluster represents sakers (SF), and the purple cluster represents saker-like Altai falcons (SLF). SP19 mitogenome is the reference mitogenome that was assembled in this project. Gray labels refer to hybrid individuals that were added to validate the W chromosome haplotype results. Sequences (labeled with the species name) were retrieved from NCBI (Accession numbers: common kestrel NC_011307.1, American kestrel NC_008547.1, merlin KM264304.1, saker NC_026715.1, peregrine 1 NC_000878.1, peregrine 2 JQ282801.1 and gyrfalcon KT989235.1).
Article Snippet: The final annotation of the assembly was done using the National Center for Biotechnology Information (NCBI) Eukaryotic Genome Annotation Pipeline, with the assembly upgraded to NCBI RefSeq assembly (GCF_015220075.1).
