Hello all, I am building some mixed models using QTLs for several traits. This basically gets at the underlying genetic architecture. However, I have a Recombinant Inbred Line (RIL) breeding design grown across 5 environments. There are a couple issues I have: 1. Each RIL is not truly independent from one another (some are more closely related than others) 2. Can measuring traits for a RIL across several environments be considered "repeated" measures?
I would definitely ask this question on the r-sig-mixed-models list. There are several packages (kinship, pedigreemm) for dealing with varying degrees of relatedness in mixed models. Ben Bolker
