When many novices first start breeding tiger skins, they don't understand anything, and they can't even tell what kind of tiger skin parrot they have. But after gradually learning about the tiger parrot, everyone also began to think about how to make their own family can match more and better breeds. Although everyone's idea is very good, it is still very difficult to implement this, and it is difficult to know how to match without a little basic knowledge. Today, Xiaobian will take you to understand the genetic inheritance of the tiger parrot, so that everyone can correctly pair and get the breed they want!
There are three main types of tiger skins that are inherited
Dominant inheritance (short version: as long as one of the parents has a dominant gene, the offspring will have the same or similar traits)
Dominantly inherited varieties include: primitive species, yellow-faced species, fish scale species, dominant special, bright flying feathers, crown feathers and so on.
Recessive inheritance (simplified version: both parents must have the same recessive gene at the same time to inherit the recessive trait to offspring)
The varieties of "recessive inheritance" include: gray-winged species, recessive specialty, Huale species, blackface species, etc.
Sex-linked (companion) inheritance (simplified version: there is a relationship between heredity and sex, the way of sex-linked inheritance is that if the male bird has a gene that can be passed on to the offspring of the female bird, the female bird inherited by the sex link cannot have the gene, either showing the phenotype of the sex link, or it is completely unrelated to the species, unlike the male bird may be with genes, it may also be phenotypic. In the case where the male bird is sexually linked, 25% of the genetic offspring are the offspring of the species, and 50% of the phenotype offspring are of the species; in the case of the female bird is sexually linked, all the offspring male birds are brought with genes, and the offspring female birds do not bring anything)
The varieties of sex-linked inheritance are: yellowing & albino species, opal species, cinnamon wing species, bright body species and so on.
First of all, let's analyze the genetic mode of the tiger parrot:
"Dominant inheritance" means that if one of the parent birds is only this breed, then the offspring will definitely appear in this breed. First of all, the color, green is the representation relative to blue, which means that as long as a blue bird is matched with a green bird, then their offspring must be green birds. This is why many birds have the highest chance of appearing with green matching. Of course, the genetic ones are a different matter.
Dominant genetic strains:
The four kinds of primitive, dominant, dominant, and crown feathers are relatively special and will not be introduced here. For example, if you take the Xianpai with fish scales, their descendants will appear Xianpai, fish scales, fish scales and primitive. Why is there a primitive? Because in dominant inheritance, the original role is similar to the background color, the offspring of dominant genetic varieties must have primitive, but the exceptions of dual-gene varieties are the following: dual-gene prominence (double manifestation), dual-gene fish scales (white and black eyes) and dual-gene yellow face, these three varieties are single-gene with the same single gene, which means that no matter what bird is matched, the offspring will have single-gene prominence, fish scales and yellow faces, and there will be no primitive. The reasons for this are more complicated, and are not too much to introduce here, because there is no foundation that is not easy to understand. Dual-gene varieties appear only in dominant inheritance. ps: dominant inheritance does not carry genes, there will be no bird belts, fish scale genes, and yellow faces are mainly related to color.
"Recessive inheritance" is what is commonly referred to as generation-by-generation inheritance. Its genetic method is that both parents must have this gene in order for offspring to have this breed. For example, if two primitives have gray-winged genes, the offspring will have gray wings, which is a quarter of the chance of gray wings. Of course, if a gray-winged phenotype is paired with a primitive grey-wing gene, the chance of gray-wingedness increases to one-half. The chance of gray wings with gray wings out of gray wings is 100 percent, and this will not be primitive.
Recessive genetic breeds: Grey-winged, Recessive Paiter (Recluse) and Hua Le, etc
Recessive genetic formula:
Common species× common species/recessive genes = 50% common species, 50% common species with recessive genes
Common species/recessive genes× common species/recessive genes = 25% common species, 50% common species with recessive genes, 25% recessive genes
Recessive genes of common species × = 100% of common species with recessive genes
Common species/recessive genes× recessive genes = 50% common species with recessive genes, 50% recessive genes
Recessive genes × recessive genes = 100% recessive genes
"Sex-linked inheritance" is also known as concomitant inheritance. This variety is inherited in a way that differs from the other two in that it involves sex because it exists on sex chromosomes, i.e. the variety and sex are directly linked. Take opal, for example, a male protein ♂ with a primitive ♀ mother will produce a parent opal ♀ and a male primitive ♂, and all the male primitives ♂ of the offspring have opal genes. Conversely, if the parent opal ♀ is matched with the male primitive ♂, the offspring will only have the primitive, and all male birds carry the opal gene ♂. To sum up: the law of sex-linked inheritance is that male birds are opals, which will make all female birds in their offspring opal, and all male birds carry opal genes. The mother bird is an opal, which will cause all male birds in the offspring to carry opal genes, while the offspring mother bird does not carry anything; both parents are opals, so the offspring only have opals.
Sex-linked genetic varieties: opal, cinnamon, albino yellowing, and leukosomes.
Sex-linked genetic formula:
Concomitant inheritance + concomitant inheritance = 100% concomitant inheritance
Companion genetic male + common breeding mother = common species male bird with companion gene, companion female bird
Common species with companion gene male + companion gene mother = companion male, common species with companion gene male, companion mother, ordinary seed mother
Common breed male + companion female = common species with companion gene male bird, common species female bird
Common species with companion gene male bird + common species female bird = common species male bird, common species with companion gene male bird, companion female bird, common species female bird
Note: (Bright body this variety is more special, when the bright body and albino or yellowing combined, the bright body will be converted from continuous inheritance to dominant inheritance, albino yellowing will also be converted from continuous inheritance to recessive inheritance, of course, the recessive inheritance mentioned here is only relative to the bright body)
