Bambi is not essential for limb and crnaiofacial development. Skeletal preparations of the forelimb (a, b), hindlimb (c, d), and skull (e, f) were compared between wildtype (a, c, e) and Bambidel/del homozygous (b, d, f) newborn littermates. No significant difference was found. (e) and (f) show the ventral view of the skulls.
