First, it is redundant with :attr:`fwdpy11.DiploidMetadata.g` for the common case of mutational effects on a single trait. Second, we save some memory by not tracking these matrices. However, it is useful to track these data for some cases when simulating multivariate mutational effects (pleiotropy). .. note:: If recorder is None, then :class:`fwdpy11.NoAncientSamples` will be used.
