Out of the remaining tenth a great majority would be beautiful simply by "taking after" one or other parent, simply through the predominance, the prepotency, of one parent over the other, a thing that might have happened equally well if the other parent was plain. a, b, c, d, e, F, etc., and A, b, c, d, e, f, etc.,
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.
There are, no doubt, already a number of unselfish and fortunately placed men who are able to do a certain amount of work in this direction; Professor Cossar Ewart, for example, one of those fine, subtle, unhonoured workers who are the glory of British science and the condemnation of our social order, has done much to clarify the discussion of telegony and prepotency, and there are many such medical men as Mr.
By what means, then, did illegitimate unions ever become sterile? It would seem a far simpler way for each plant's pollen to have acquired a prepotency on another individual's stigma over that of the same individual, without the extraordinary complication of three differences of structure and eighteen different unions with varying degrees of sterility!
Again, we have seen that a tendency exists in nature to eliminate hybrid races, by whatever means that elimination is effected, while no similar tendency bars the way to an indefinite blending of varieties. This has also been enforced by statements as to the prepotency of certain pollen of identical species, but of distinct races.
And even after Fate or a gust of passion has whirled her into the arms of our busy and capable fundamental man, all these things will still be in her imagination and memory. Unless he is a person of extraordinary mental prepotency, she will almost insensibly determine the character of the home in a direction quite other than that of our first sketch.
The goose. The peacock. The guinea fowl. Exceptional causes of variation under domestication. Alleged tendency to reversion. Instances. Sterility of hybrids. Prepotency of pollen of same species, but of different race. Mortality in young gallinaceous hybrids. A bar to intermixture exists somewhere. Guinea-pigs. Summary and conclusion.
In all these cases we do not have abortions or monstrosities, but more or less harmonious forms often of great functional activity, endowed with marked viability and generative prepotency, except in the case of hybrids, when we often find even a more marked generative impotency.
To the prepotency of this distinguished divine, General Smith often, in a tone of mingled banter and seriousness, attributed not only his habit of mature reflection and love of learning, but also his "moderation combined with firmness" upon all questions which engaged his attention.
Thus, we necessarily select the only trait really worth while; that is prepotency or the ability to beget desirable qualities. The application of this centgenitor system necessitates inbreeding; it also necessitates large operations. Of the former, breeders have generally been afraid; of the latter they have lacked opportunity.
