(B) Histogram of the GC content of human TFRs. Area indicated in blue describes the subset of TFRs that have an orthologous TFR in zebrafish larger than 10 kb, the area in red have an orthologous TFR in zebrafish larger than 5 kb. (C) Scatter plot of the GC content of orthologous pairs of zebrafish and human TFRs ≥ 10 kb in both species. Points in red indicate TFR pairs with a difference of absolute GC% greater than 20
