But it does not follow from this that in each particular case certain characters will reappear; for instance, this will not occur when a race is crossed with another endowed with prepotency of transmission.
The rate of absorption must also depend on the amount of distinguishable difference between the two forms which are crossed, and especially, as Gartner insists, on prepotency of transmission in the one form over the other.
It is obvious, that a purely-bred form of either sex, in all cases in which prepotency does not run more strongly in one sex than the other, will transmit its character with prepotent force over a mongrelised and already variable form.
Prepotency of transmission may be equal in the two sexes of the same species, but often runs more strongly in one sex.
It is remarkable that the prepotency of one species over another in transmission is quite independent, as shown by Gartner, of the greater or less facility with which the one fertilises the other.
The explanation of this form of prepotency will be obvious when we come to the consideration of Reversion.
It depends on the difference in the strength or prepotency of transmission in the two parent-forms, on their actual amount of difference, and on the nature of the conditions of life to which the crossed offspring are exposed.
The truth of the principle of prepotency comes out more clearly when distinct races are crossed.
Prepotency of pollen of same species, but of different race.
This has also been enforced by statements as to theprepotency of certain pollen of identical species, but of distinct races.
Prepotency of and physical likeness to her mother.
Moral prepotency of and physical resemblance to his mother.
Moral prepotencyof his father, physical likeness to his mother.
An adjunction of characteristics, moral prepotency of his father, physical likeness to his mother.
Prepotency of her father, physical likeness to her mother.
Prepotency of his mother, whom he physically resembles.
Moral prepotency of and physical likeness to his father.
All this I attributed to that 'prepotency of transmission in descent' which I knew to be one of the Romany characteristics.
But so absorbed was I in my struggle with Fenella Stanley and Romany superstitions, that the only subject which could distract me from memory was that of hereditary influence--prepotency of transmission in relation to races.
This rapid fall while exposed to oblique sunshine is quite in harmony with the rapid loss of heat during the few hours of darkness during an eclipse, both showing the prepotency of radiation over insolation on the moon.
Hereupon quoth Yusuf to himself, "By Allah, none founded this puissant fortalice in such power and prepotency and forcefulness save for a mighty matter and a cause of much consequence.
Thirdly, prepotency of transmission, which may be confined to one sex, or be common to both sexes of the prepotent form.
The law of prepotency comes into action when species are crossed, as with races and individuals.
But it does not follow from this that in each particular case certain characters will reappear: for instance, this will not occur when a race is crossed with another endowed with prepotency of transmission.
STURM, prepotency of transmission of characters in sheep and cattle, ii.
The truth of the principle of prepotency comes out more clearly when certain races are crossed.
The rate of absorption must also depend on the amount of distinguishable difference between the two forms which are crossed, and especially, as Gärtner insists, on prepotency of transmission in the one form over the other.
So it must be, owing merely to the prepotency of foreign pollen, with cabbages and various other plants, the varieties of which almost invariably intercross when grown together.
Scarcely any result from my experiments has surprised me so much as this of the prepotency of pollen from a distinct individual over each plant's own pollen, as proved by the greater constitutional vigour of the crossed seedlings.
The following observations were made on a healthy specimen of Aurelia having all its lithocysts in good condition, but prepotency being well marked in the case of one of them, and also, though in a lesser degree, in the case of another.
Nevertheless, in many cases such prepotency cannot, even with the greatest care, be observed; but upon every pulsation all parts of the swimming-bell seem to contract at the same instant.
This is not the case with segment B; probably the degree of prepotency of the lithocyst in this case was not sufficient to counteract the antagonistic influence of the small size of the segment.
The only other motion exhibited by Echini thus situated is that of a slow rolling movement, now to one side and now to another, according to the prepotency of the pull exerted by this or that row of ambulacral feet.
It is in this power of prepotency that one of the chief benefits from the use of a pure bred sire or dam arises.
We find their parallel in Florentine history in the ottimati, the nobili popolani, whose prepotency had been overthrown by the Medici more than half a century before.
But this epoch of Ghibelline prepotency in Tuscany was brief.
In the same year peace was finally made with Florence, and a confederation established between the two Republics, Montepulciano being restored and the prepotency of the Petrucci assured.
Professor Ewart, however, believes that inbreeding is much commoner among wild animals than has usually been conceded, and he holds the opinion that the prepotency so induced has played a considerable part in the origin of species.
Can you doubt, after duly considering the facts of prepotencyon the one hand and those of Jordan's physiological varieties on the other, that cross-infertility does arise before or during the specific differentiation?
I attach considerable importance to the phenomena of prepotency in view of the contrast which is presented between plants and animals in the relation of their species to physical barriers.
Both from Kerner's work, and still more from that of Jordan and Naegeli, I conclude that (at all events in plants) prepotency is the way in which physiological selection chiefly acts.
And when we remember on how delicate a balance of physiological conditions complete correspondency of pollen to ovules depends, we may be prepared to expect that the phenomenon of prepotency is not of uncommon occurrence.
Even if such a thing could be imagined as happening occasionally, I feel it difficult to imagine that it can happen habitually, and yet this view must be held by those who would attribute prepotency to natural selection.
For example, the phenomena of prepotency (whether as between varieties or between closely allied species) are found to occur when the two forms occupy a common area, i.
