Curve of cumulative probability of Chi-square values for number of heterozygous loci or shared alleles. Red line is where the critical value lies for the confidence level of 95%; while the blue one is the test statistic. a, b are figures for unlinked data; c, d are figures for fully linked data. In (c) and (d), the test statistic is far larger than the critical value, and beyond the limit of x-axis
