Having been approved by the canary Arlequim Technical Canaries Porte of the Portuguese College of Judges of Ornithology, lends itself to this bird in the genetic study of this phenomenon and propedeutic mutant that call saves. It is involved in mysteries and myths, particularly in relation to lethal factor. Among many other issues phenomenon raises the question arises: why the save is a factor and lethal not stressed?

SOME CONSIDERATIONS

The fact that first attracted our attention was the fact that there is in Nature no saves with the characteristics of the canaries hoopoes that is known to develop from a central point or a risk, Sheung centrifugally. The sum of this data is another no less spectacular: you save the birds cultivated by man are all of type: canaries, bengalins, finches and parakeets have wavy you save the format above. We say that there are slight changes, such as the old Lancashire, but the trails are of little rides in relation to our study.

These two elements and this raises important questions: what is to be to save the canaries?

From the morphological point of view is easy to answer the question and we all know as it may appear. The creators believe that, if not regular, as described above, is faulty. Say defective because meets the established canons.

From the standpoint of microscopic and histological consists of a swirl of feathers that emerge obliquely to the surface of penalty which, incidentally, also occurs in human hair: straight hair  emerge perpendicular to the surface of the scalp and the wavy or kinky emerge obliquely.

But what gives rise to this change in the direction of the feathers? That is the question. This is just one variety, or an anomaly, or a disease?

It is widely reported the lethal effect of the gene saves. Interested in a serious study, from all doubts. Most of the books accept tradition that mating with saves saves expresses the lethal effect.

But many writers confess they have no personal experience and many creators say the same. Accept, because it is traditional. Alvaro Rebelo states that several years two mated Gloster corona because had time for a bird to mate consort. Born birds saves irregular. Also a creator of Setubal, states that mated bengalins of saves with bengalins of spares with good results. It is said that the initial Lancashire disappeared because of the saves, putting aside the difficulty of creating and weakness due to large and even factors of the two Great Wars, as is known, almost did remove the Lizard. The save is at fault for everything.

I decided therefore to start a search from scratch, mating birds to save to save birds: canaries, bengalins, finches and parakeets wavy.

What is strange is that the same effect as a result of the swirl origin of feathers, is only taken as lethal as the saving in relation to stressed, which has a similar origin, is not perceived as lethal.

However I studied theoretical hypothesis because available a canary that mated with multiple males without saving, just gave me children with spares.

From the laws of Mendel, and putting aside the cases that do not respect to what interests us, let us see the possibilities:

Assuming birds dominant factor, without lethal factor. As is known, the birds with phenotype X may result from:

1 - X of both parents (homozygous)

2 - X of one parent (dominant) and a parent Y (recessive) (heterozygous)

We, therefore, that a bird of X phenotype may result from the mating of homozygotes (case 1) or the mating of birds heterozygous (case 2)

In the case of a lethal factor:

It is generally accepted that the mating of two birds with lethal factor Results:

25% of birds viable (A)

50% of birds with dominant phenotype, but heterozygous (B)

25% of birds with recessive phenotype (C)

From this knowledge we can work with either birds dominant phenotype or with birds of recessive phenotype.

Thus:

Mating B to B, we get the same pattern as above, where the select only birds B. But this is different from the mating first because the result of birds with B. B Again with the children and so turn, will make the phenotype more and more approximate genotypic point of view.

Mating C and C can only get birds C.

In the case before us, namely the study of hoopoes, we are conduct, in 1999, the mating of birds with saves saves the first generation (canaries, finches and bengalins). Of the newborns, mate ever, in future generations, save with no saves and saves with no saves.

After the breeding season of canaries can say the following: In a couple of canaries we obtained two creations with the following result:

1st creation - 5 eggs all full of birds that were born 5, with 3 saves and 2 without saving.

2nd creation - 5 eggs all full of birds that were born 5, with 3 saves and 2 without saving.

In this experiment, which was initiated too late in relation to the creations of years, we conclude that all birds are viable and without deformities.

Meanwhile we await the results between the bengalins and the mandarins and proceed with the experiments with the canaries in the next year.
