* p < 0.01 (Wilcoxon test for comparison with autosomal genes) Gene length: length of transcribed DNA sequence from most upstream transcriptional start site to most downstream transcriptional termination site; intergenic region: For this, the intergenic segments between any two genes were cut into two halves. Each of them was assigned to the closest gene. As intergenic region of a gene we then added the lengths of the halved upstream intergenic segment and of the halved downstream intergenic segment. Since the features show a highly skewed distribution, medians are given instead of averages and standard deviations. |
