aNumber of sets of cMegaBAC-CGCs with consecutive numbers and same orientation as in the human genome. bPredicted lengths of chromosomes after removal of large gaps, >1 Mb, in the human genome sequence. cMap lengths calculated from Sheep Map 4.6 using the sex-averaged lengths, except for the X chromosome where the length of the female map was used. dChromosome lengths calculated from the sheep ISCNDB (2000) standard cytogenetic maps [47], assuming a genome size, excluding the Y chromosome, of 3 Gb. BAC, bacterial artificial chromosome; CGC, comparative genome contig; Gb, gigabases; HSA, human chromosome; Mb, megabases; OAR, sheep chromosome.
