Hello all, I've become involved in a small student project looking at spatial variation in a very, very young group. There's discordance between the mtDNA and nDNA trees, and good estimates of admixture based on population genetic studies, between the different lineages (both mt and n lineages).
I'm modeling size differences between lineages and attempting to detect clear shifts in both average body size and sexual dimorphism. I don't see any reason *per se* that a covariance structure based on admixture rates (rather than strictly from the tree) wouldn't work, and it would *seem*to allow for a not-strictly-bifurcating population history I suspect is the case here...but I can't find anyone who has done something similar! Am I blind and there's some obvious paper I'm missing where covariance between lineages was determined from something like admixture rates, or is it a silly idea and I should just use the tree as an "average" covariance and call it a day?
