  1. ALD, average inter-locus distance; '1' the homologous zebrafish chromosome that share at least two markers in common with a given grass carp linkage group; '2', the number of syntenic loci in one pair of grass carp LG and homologous zebrafish chromosome; R, the ratio of syntenic region to displayed region of reference chromosome (Mb) in NIH genetic sequence database http://blast.ncbi.nlm.nih.gov/Blast.cgi; Length of syntenic region (Mb) was calculated based on the distance between the longest syntenic pair of loci in each homologous zebrafish chromosome.
