The human doublet duplications and their matched mouse segments. Each green bar is a mouse chromosome, labeled with the chromosome name. The human chromosomes are shown as gray bars with the name above or under the bars. Each black vertical bar represents a mouse or human segment. The red or blue line between two vertical bars means a match relationship, where red and green mean that separate human segments match the same mouse segment. The horizontal length of the bar is proportional to the sequence length. Only segments related to the mouse autosomal chromosomes and the human duplications found in NCBI human genome build 30 are shown.
