图1. 多态性的SNP在染色体上的分布
每一个黄色条带代表一条染色体,黑线代表多态性SNP定位的位置;横坐标为染色体长度,按照1 M的大小对基因组进行划分。黑色越深代表SNP标记数越多,颜色越深的区域即SNP标记集中分布的区域
Fig. 1. The distribution of polymorphic SNP in 17 chromosomes
Every yellow band indicated one chromosome, and black line indicated the position of SNP. The abscissa is the length of the chromosome, and the genome was divided by every 1M. The darker position represented more SNPs, and the darker regions showed the centralized distribution area of SNPs
