Standard errors of sexual dimorphism?
...ferent traits in four populations (a total of 28 SD-estimates). We have used the following formula for estimating SD: 100 * (mean male trait value - mean female trait value)/overall trait mean). Then, we have used these SD-estimates to perform a GLM against other interesting variables, such as the intersexual genetic correlations for each of the traits. Here are my questions: 1. Is there any procedure in "R" you would recommend that takes in to account the sampling variance of the SD-estimates, rather than using the mean value of each (which is supposed to reduce error and increase Type I-er...

Question about random interactions in MCMCglmm
Hi, I've been a bit confused by different wyas we specify random effects in lmer and MCMCglmm i just want to clear something. When I want to look for intersexual genetic correlations in the trait, is it equivalent to treat this trait for opposite sexes as separate traits and include the term idh(trait):animal - to treating this as a single trait and fitting idh(sex):animal? Do these two ways of specyfying random effects differ in this case? Cheers, sz.
