Repetitive DNA content in Cot and genomic sequences. (A) Distribution of repeats based on estimated copy numbers for the entire chicken genome (see Results). The y-axis indicates the percentage of sequences that contain a respective repeat class for each Cot fraction. The class “No Hit” refers to sequences that had no match in the publicly available genome sequence. (B) Repeat and gene coding sequences (CDS) content of chicken chromosomes. The repeat and gene content was calculated in windows of 500 kb along the chromosomes. Note that the scale for the CDS content differs from the one for the repeat content. (C) Average repeat and gene content for individual chicken chromosomes. The chromosomes are ordered by size with the largest chromosome (Chromosome 1) on the left and the smallest (Chromosome 16) on the right. Chromosomes and fragments of chromosomes smaller than 1 Mbp are not included.
