p -Value Cutoff for Segregation Test Plots
Use this text box to specify an alpha value (false positive rate) for testing significant deviations of the segregation ratios from expected values.
Alpha must be a real number between 0 and 1 .
A Volcano Plot showing the p-values for the chi-square goodness of fit test for the segregation ratios plotted against the difference in the frequencies of the A allele ( P1 line) versus the B allele ( P2 line) is generated as part of the output of this process. A horizontal reference line corresponding to the alpha value (converted to -log 10 scale) entered here is shown in the resulting volcano plot .
To Specify the p -Value Cutoff for the Segregation Test Plots:

Type the desired alpha value in the text box.
