Fig. 1

Relative sequencing depth of scaffolds in a female and a male white-tailed eagle. Relative scaffold depth was estimated as mode of scaffold depth / overall genomic depth, which was 195 for the female and 181 for the male. The shading of the dots, representing scaffolds, refer to whether they map to the Z or autosomal (A) chromosomes in the golden eagle genome with known chromosomes. A Relative depth in the female. B The male to female ratio (rmf) of relative scaffold depth after filtering (removing scaffolds with relative depth outside the range of 0.25–1.5 in either the male or female). C Relative depth in the male. D The male to female ratio (rmf) of relative depth for all scaffolds. In A and C the dashed line represents the scaffold size threshold value of 198,789 bases (log10 5.29). In A and C, points lower than the threshold value of 198,789 bases displayed high variation for relative depth (Fig. S2). Scaffolds below the threshold in A and B make up 1.1% of data, only 0.0071% is below the threshold and above a relative depth of 3. Dashed line in B and D is 1.5, which is right between expectation for autosomal (1) and Z chromosomes scaffolds (2). “0951”, “0990”, “1047”, and “1051”, in A, B, and D, refers to the scaffolds NW_011950951.1, NW_011950990.1, NW_011951047.1 and NW_011951051.1
