Graphical tests for Hardy-Weinberg equilibrium based on the ternary plot
J Graffelman, JM Camarena - Human heredity, 2007 - karger.com
Objective: We design a graphical test for Hardy-Weinberg equilibrium. This can circumvent
the calculation of p values and the statistical (non) significance of a large number of biallelic …
