MacDougal also obtained a more or less distinct mutant of Oenothera biennis.
This, however, is not so essential as to decide whether themutant stands in any relation to the influence of external factors.
Another mutant leap and there was comprehension of other worlds, of other stars.
Two mutant genes can start reactions that end up as a man with one leg, or maybe as a bull with the intelligence of an eight-year-old man.
But, when two like mutant genes come together in reproduction, the animal is bound to be something different, the way you eleven calves are.
The cool and humid belt suited to the propagation of the blond mutant (and its blond hybrids) would shift northward and shorten down to the seaboard as the glacial conditions in which it had originated presently ceased.
It follows that, in point of pedigree, according to this view there neither is nor ever has been a pure-bred dolicho-blond individual since the putative original mutant with which the type came in.
I have already mentioned that the rapid production of large numbers of new varieties, by [626] means of the crossing of the offspring of a single mutant with previously existing sorts, is a very common feature in horticultural practice.
One of the great points of pedigree-culture is the fact that the ancestors of every mutant have been controlled and recorded.
Nor did Travis guess that at this point he had already traveled far beyond the expectations of the men who had bred and trained the two mutant coyotes.
Any tribe led by Deklay would be hostile to themutant animals.
The total proportion of mutant plants compared with the normal was 1.
Normally the third segment bears minute appendages which are the vestiges of the second pair of wings; in the mutant the wings of the third segment are true wings though imperfectly developed.
The first mutant to be recognised--in 1887--was one called lata.
Cœlum non animum mutant qui trans mare currunt=--Those who cross the sea change only the climate, not their character.
Are you themutant they're always speculating about?
Nothing is more likely than that the mutant was an ordinary recessive.
The fact that the two forms, laeta and velutina, are produced by many matings in which Lamarckiana and its mutant rubrinervis are used as males is confirmed abundantly by Honing, who has carried out extensive researches on the subject.
Couldn't you get a fix on this frequency that controls your mutant powers and locate the space station that way?
The recuperative powers of a mutant were in action.
Yesterday, when he was so tired, I almost gave him back his mutant powers.
The female you saw, the one you thought was a Lyrian, was a mutant from the other group.
When the book fell, hermutant powers would be gone.
After the first mutant wave had been captured, the switch would be thrown to the left.
Walt, the most adept mutant in the compartment, listened attentively and then began to heal John.
He realized that he was in the Mutant Quarter, not far from Myla's house.
This was what the robot-confessor had tried to warn him about, and what the mutant girl had skrenned.
Barrent nodded his thanks before he noticed that the girl was not Moera; she was the skrenning mutant who had predicted his death.
They lived in the Mutant Quarter, which was almost a self-contained city within Tetrahyde.
When roving mobs were formed to have a little fun in the Mutant Quarter, Barrent usually pleaded a headache.
Late one night, suitably cloaked and armed, he left his apartment and went to the Mutant Quarter.
Barrent paused, thinking about the stories he had heard of gullible citizens falling into mutant hands.
These characters furnish a good illustration of the fact that mutant gens ordinarily affect many parts of the body, though these secondary effects often pass unnoticed.
The system of symbols used in the diagrams and table headings is as follows: The factor or gen for a recessive mutant character is represented by a lower-case letter, as v for vermilion and m for miniature.
The answer is found in the way in which the mutantfactors arise.
In the mutant called "fused" the females are sterile both with wild males and with males from their own stock.
A few males of a new mutant with a lemon-colored body and wings appeared in August 1912.
If the viability of each mutant type could be determined in relation to the viability of the normal, "coefficients of viability" could serve as corrections in working with the various mutant characters.
Most of the mutant types of Drosophila show characteristics that may be regarded as superficial in so far as they do not prevent the animal from living in the protected life that our cultures afford.
Similar results were found in the mutant type called reduplicated legs, which is a sex-linked recessive character that appears best when the cultures are kept at about 10deg C.
Furthermore, it is possible that there occasionally arises what may be called a mutant of very desirable character from a eugenic point of view.
Again, a mutant stock in the fruit fly (Drosophila) has as its most marked characteristic very short wings.
For example, a mutant stock called rudimentary wings has as its principle characteristic very short wings (fig.
In the fourth figure (d) the mutant called dichaete is shown.
For example, a mutant type called truncate appeared, characterized by shorter wings, usually square at the end, (fig.
Without colored figures it is not possible to show many of the most striking differences of these mutant races; at most dark and light coloring can be indicated by the shading of the body, wings, or eyes.
Amongst the new mutant factors there may be some whose chief effect is on the character that the breeder is already selecting.
We have seen that there are thirty mutant factors at least that have an influence on eye color, and it is probable that there are at least as many normal factors that are involved in the production of the red eye of the wild fly.
This mutant is likewise very variable, often indistinguishable from the wild type, yet when well developed strikingly different from any other mutant.
There are two mutant races in our cultures of the fruit fly Drosophila that have dark body color, one called sooty, another which is even blacker, called ebony (fig.
Since they breed true and follow Mendel's laws it is possible to combine them with characters of the wild type or with those of other mutant races.
