Genetic Power Calculator
QTL Association for Sibships
Note : By default, power is calculated for a 2 degree of freedom test, testing for
additive QTL effects as well as dominance. If the No dominance button is
checked then only the additive QTL effects are tested. Note, that this implicitly
sets the dominance:additive effects ratio to 0. That is, if you do not test for
dominance, then you cannot specify it in the model.
Note : sibling correlation must be greater than or equal to half of
the additive genetic variance and one quarter of the dominance genetic
variance. If this condition is not met, the shared residual variance
will be negative (this can be easily checked in the ouput).
