Phenotypic analysis of fetuses harvested from embryo transfers (ETs). (a) Fetuses from ET 1, (b) 2 and (c) 4 along with aged matched horned and polled controls. Fetuses were harvested at 151, 123 and 95 days of gestation, respectively. Horn bud development can be seen by the presence of small dimples (black arrows).
