Recent segmental and gene duplications in the mouse genome

Table 2 Comparison between genome assemblies

Sequence identity level	February 2002 assembly*	February 2003 assembly
Duplication content (bp)
90-92%	4,966,470	3,543,429
92-94%	15,685,840	13,981,642
94-96%	17,533,730	17,970,287
96-98%	11,539,392	11,731,958
98-99.5%	5,865,024	5,487,899
^†Potential sequence misassignment error detected (bp)
99.5-100%	4,832,594	18,456,096

The comparison is of duplication content by sequence identity and potential sequence misassignment errors between the February 2002 (MGSCv3) and February 2003 (a hybrid assembly of MGSCv3 with 705 Mb finished BAC sequence) genome assemblies. *Analysis of the duplication content for February 2002 assembly can be found at [14].^†Sequences detected to show extremely high percent identity duplications are likely to be genome assembly artifacts and were not included in the duplication content shown in Table 1.
