Fig. 7

Seven factors were considered in the selection of the 10 most reliable markers. Each factor corresponds to one of seven circles. A number from 1 to 7 was assigned to each circle from the outside to the inside. The first circle represents 29 autosomes, 1 X chromosome and 1 extra chromosome used to carry the contigs that were not assigned to chromosomes. The third circle is representative of the gene names; while the histogram shown in the second circle aligned with the third circle which represented the number of loci in this gene. Each gene corresponded to two bars: the left blue bar indicated the number of loci resided in this gene and the right purple bar indicated the loci located at the outside of the gene but within 5 kb of the gene. The 4th, 5th, 6th and 7th circles were aligned with each other and represented the conditions of each locus. The locus whose genotype was homozygous is shown as a black line in the fourth circle. The number of haplotypes for a locus was represented by the length of this locus’ bar at the 5th, 6th, and 7th circle corresponding to the YC-ZC population, the YC population and the ZC population, respectively
