*Each IMFS sequence was assembled using the generated sequences from two or more BACs (except for IMFS5, which was derived from a single BAC sequence). The indicated GenBank accession numbers correspond to the assembled sequences (also see Figures 3 and 6). ^†Length of the assembled IMFS sequence. ^‡Total number of gaps within the sequences of the individual BACs used to generate the IMFS sequence. Note that there are no gaps in the regions spanning the telomeric and satellite I repeats. ^§Total size of (TTAGGG)_n block within the assembled IMFS sequence. In some cases, the (TTAGGG)_n blocks are interspersed with other sequences, in which case more than one size is given. ^¶Total amount of satellite I sequence (present in a single block except in the case of IMFS2 and IMFS4; Figure 3). ^¥Indian muntjac chromosome localization, as determined by FISH studies of individual BACs (Table 3). ^#A similar repeat, (TTCGGG)_n, resides immediately adjacent to the (TTAGGG)_n block. **Satellite I sequence resides in a single block that is interrupted by L1 and MER66-int LTR/ERV1 repeats. ^††The chromosome fusion site within IMFS7 contains a region of 100% sequence identity with TGS400 [19].
