Genotype division on oil/protein phenotype by Strategy A on SNP Gm07_15667842_T_C and Gm07_15662403_C_T. Y presents the protein content; X presents the oil content, and each point represents the phenotype of one sample in the soybean population. Genotypes of the samples are depicted using pairwise SNP combinations in different shapes and colors, where 0 and 2 represent major and minor alleles in homozygous, respectively, while 1 presents heterozygous. The numbers in parentheses show the number of samples and percentage. We can see the genotype 00 (blue dots) and 22 (red dots) have clear phenotype (protein and oil) features
