variety. For instance, I think those authors are right, who maintain that the ass has a prepotent power over the horse, so that both the mule and the hinny more resemble
the ass than the horse; but that the prepotency runs more strongly in the male-ass
than in the female,
so
that the mule, which is the offspring of the male-ass
and mare, is more like an ass, than is the hinny, which is the offspring of the female-ass and stallion. |

Much stress has been laid by some authors on the supposed fact, that mongrel animals alone are born closely like
one of their parents; but it can be shown that
this does sometimes occur with hybrids;
yet I grant much less frequently with hybrids
than with mongrels. Looking to the cases which I have collected of cross-bred animals closely resembling one parent, the resemblances seem chiefly confined to characters almost monstrous in their nature, and which have suddenly appeared—
such
as albinism, melanism, deficiency of tail or horns, or additional fingers and toes; and do not relate to characters which have been slowly acquired by
selection. Consequently,
sudden reversions to the perfect character of either parent would
be
more
likely to occur with mongrels, which are descended from varieties often suddenly produced and semi-monstrous in character, than with hybrids, which are descended from species slowly and naturally produced. On the whole
I entirely agree with Dr. Prosper Lucas, who, after arranging an enormous body of facts with respect to animals, comes to the conclusion, that the laws of resemblance of the child to its parents are the same, whether the two parents differ much
or little
from each other, namely
in the union of individuals of the same variety, or of different varieties, or of distinct species. |
