A)
The group loses all of its original traits.
B)
The genetic diversity of the group is reduced.
C)
The genetic material may be rejected by the group.
D)
A disease in recessive form could be introduced into the group.

I think it is C. By mating stock that are unrelated, the chance of intensifying undesirable traits is minimized. Unfortunately, due to the heterozygous, or dissimilar, genetic nature of a group of unrelated stock, the chance of intensifying desirable traits is likewise diminished. In theory, stock that are the product of outcrossing programs (Also called Crossbreeding) may be more heterozygous than inbred stock. Crossbreds might be outstanding performers, but as breeding stock, they will not pass on their desirable characteristics consistently.
