He thinks that only continued breeding of these apparent mutants through several generations can afford convincing evidence that we are here dealing with mutants rather than with merely pathological variations.
From the outset, therefore, the community or communities in which the blond mutants were propagated would be made up of a mixture of blond and brunet, with the brunet greatly preponderating.
It results that these surviving mutants will not have been isolated from the parent stock, and so could not breed in isolation, but must forthwith be crossed on the parent stock and could therefore yield none but hybrid offspring.

We select the most desirable mutantsand we try to fix a given type by grafting and propagating.
Under such circumstances mutants may be permitted by natural selection to survive, whereas in other parts of the world such mutants have not been able to hold their own.
On the other hand, natural selection will tend to diminish the number of species which have arisen through mutation, inasmuch as it weeds out many mutants which would have perished had their survival been determined by lot.
He spoke English with an accent that the mutants (who had learned the language from him) could not even imitate.
But she was not completely certain that she could trust him; even the tiniest doubt was an excuse not to--since there was no overwhelming advantage to be gained from having two mutants instead of one in the Pentagon.

Lycan had just finished issuing clothing to the mutants in the larger compartment.
Shortly after Walt had healed John, the mutants of the smaller compartment gathered at the observation screen in the floor--or what was to them the floor: it was actually the broad rim of the wheel.
The one called Julia had to be under the influence of the larger transmitter; all the mutants had been bred for that frequency.
The eye of the wild original fly is red, one of the mutants has a white eye, i.
Morgan, with all his mutations of the adult Drosophila, says nothing of mutants possessing legs.
Nine of these mutants have been recognised and defined, and distinguished by different names.
The answer is that in the mutants the determinants for pigmentation are united with the determinants for the lower side of the fish.
It was now the fifth generation of my pedigree, and thus I was absolutely sure that the descendants of the mutants of this year had been pure and without deviation for at least four successive generations.
In previous lectures I have mentioned that I have saved the seeds of the mutants whenever possible, and have always obtained repetitions of the prototype only.
The mutants are constant when propagated by seed, and at once constitute a new race.
Not caring to confess a lack of close observation, the number of mutantsin such cases is usually kept secret.
The offspring of my mutants are, of course, subject to the general laws of fluctuating variability.
Owing partly to improved methods of selection, [555] partly no doubt to chance, even more mutants were found this year than in the former.
In this case the mutants of one type, appearing in the same year, would not be a pure type, but would exhibit different degrees of deviation from the parent.
Instead of figuring a fan of mutants for each year, we must condense all the succeeding swarms into one single fan, as might be done also for Draba verna and other polymorphous species.
This conclusion was strengthened by the results of the next three generations, which were made on a much smaller scale and yielded the same, or at least the mutants most commonly seen in previous years.
Whenever possible, the original mutants have been isolated during the flowering period and artificially self-fertilized.
Moreover the seeds from which the mutants spring, escape observation.
See MacDougal, Vail, Shull, and Small: Mutants and Hybrids of the Oenotheras.
Group IV Only two mutants have been obtained that do not belong to any of the preceding groups; these are put together in Group IV.
These, like the mutants in Drosophila, are fully equipped at the start.
While the cause of mutants has not yet been revealed, we have already seen that the two remaining kinds of variability are due to changes in the environment, or to crossing.
Hundreds of sports or mutants have been recognized and isolated, so that many of our most valuable garden plants have arisen through this ability of plants to vary in often sudden and rather startling degree.

Two of the mutants came from an ovary which had been treated with a ten per cent.
He argues further that many of the distinctions between the mutants are quantitative in nature.
If a species is liable to be constantly associated with a mutational form, the mutants are picked out, regardless of the circumstances of their origin, from the samples among which they were captured, and put apart under a special name.
This conclusion will recall the similar problem raised by the Oenothera mutants (Chap.
Other people believed that mutants had no unusual abilities at all.

Mutants were forbidden by law to carry arms; but like this old man, most of them had heavy, iron-headed walking sticks.
In this paper we shall consider only the members of the first chromosome, describing a large number of new mutants with their linkage relations and summarizing to date all the linkage data relating to the first chromosome.
The second of these wing mutants to appear was jaunty (second chromosome), in which the wings turn up sharply at the tip; they lie in the normal position.
A most significant fact in regard to the linkage shown by the Drosophila mutants is that the number of linked groups corresponds to the number of pairs of the chromosomes.
If dominance is supposed to be a criterion as to "presence," then it should be pointed out that among the mutants of Drosophila a number of dominant types occur.
If the normal allelomorph is thought of as the positive character, which one of the mutants is due to its loss or to its absence?
In regard to the first point, several of the mutants are characterized by what seem to be additions.
For the majority of mutants which did well even under heavy competition in mass cultures the pair-breeding method reduced the disturbances due to viability to a point where they were negligible.
It is true a few mutants have been found in other Drosophilas, but relatively few as compared with the number in D.
The first mutants were found in the spring of 1910.
If mutants started reproducing, that could be a real threat in a world whose economy is so delicately balanced.
