  • a Number of human kilobases labeled by RepeatMasker as belonging to the given family and present in the Boreoeutherian ancestor

  • b Number of human kilobases that are not detected as repetitive in human, but that are detected as such in the corresponding ancestral region. All numbers were calculated using the sensitive mode of RepeatMasker
