For Kristin:


I have genotype and phenotype data for persons with a disease, their healthy siblings, and unrelated healthy controls. Since the genotypes between affected persons and siblings are correlated, I need to create a random effect for family membership. I am trying to run a mixed anova with fixed effect(genotype) and random effect(family). I want to get an F-test for effect of genotype on phenotype.

I have read the documentation for anova, and the description says it does mixed-effects anovas, but there's no example of it, so I am not sure how to specify the model.
