Anury is the absence or abbreviation of the tail in sheep (and also other animals). It is inherited in an autosomal dominant fashion. A ram with anury is mated to a ewe with a normal tail. The ram’s father had anury, his mother did not. What is the probability that the ram and ewe will produce a lamb with anury? (ram = male; ewe = female)
