... When a calf inherits 2 copies of the AM or NH alleles their development is so adversely affected that they will be still-born. In other cases, such as CA and DD, calves carrying 2 copies of the broken allele may reach full-term. In such cases the animal may either appear relatively normal, or show p ...
