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?
