I may have missed a few exchanges but I haven't seen anyone mention last
spring's big splash in _Nature_ about the congenital inheritance of "male
mimicking" genitalia in female hyenas. It seems like the classic case to

There's also the case of handedness which I've heard may be related to the
site of implantation in the uterus. This is a bit more distant from the
original question as it is the proportion in the population which remains
constant, rather than generation to generation consistency in inheritance.
Sort of the opposite of the apple seed example in that no matter how much
right or left handedness would be selected against, the ratios might be
impervious to selection (so, presumably if right handedness were to cause
death within the first year, the species would probably go extinct within
a few generations as only 10%-25% of each generation would even
potentially survive to reproduce).
