Descriptive statistics of the NCBI mammalian NUMTs. (a) Correlation between NUMT length/count and nuclear genome size in Mb. (b) Correlation between NUMT length/count and total nuclear genome GC content (%). (c) The relative GC contents of NUMTs and their corresponding mitochondrial sequences compared to the GC content of total nuclear genome and total mtDNA genome GC contents respectively. (d) Distributions of relative and absolute NUMT sizes. Relativization was performed based on the corresponding mtDNA genome size
