A mutation is in a way a sudden and unforeseen change in the physical appearance of the offspring of a pair of parakeets. It is not caused by an external factor (light or dark, food), either the environment or living conditions.
This takes place on the genetic basis of the budgie. Chromosomes are composed of genes and are the concrete carriers of hereditary traits. Those responsible for an individual’s sex are the sex chromosomes. In the mammalian world, the male carries two different chromosomes named X and Y. The female will carry identical chromosomes named X and X. In birds it is the opposite, the male is XX and the female is XY.
The mutation is therefore an accidental change in the number of chromosomes or the shape of one of them. Or because of the alteration of a gene.
In budgies, mutations are colored and sometimes shaped (for example, the wavy crested parakeet). These mutations are hereditary, and they are recognized from the birth of the parakeet, they can not occur in adulthood.
Let’s get down to business, with some vocabulary first and foremost to understand what’s next:
- Homozygous: budgie which for a chosen trait carries the same gene on each chromosome of the chromosomal pair (chromosomes are always in pairs)
- Heterozygous: budgie that has on a pair of chromosomes the character of a mutation on only one of the two chromosomes.
- Chromosome: structure made up of DNA. Each of the chromosomes has a different shape.
- Gene: detailed composition of the chromosome at a specific location
- Phenotype: appearance. The set of observable characteristics of an individual. Thephenotypecorresponds to the realization of the genotype (gene expression).
- Carrier: budgie that contains the character of a mutation, but it is not expressed visually (because it is heterozygous and the mutation is recessive).
We will therefore illustrate the parakeet and its pair of chromosomes carrying the mutation:
The dominant mutation A dominant mutation means that on the pair of chromosomes, only one can carry the mutation, the mutation dominates (despite the heterozygous appearance) and is therefore physically visible, on the parakeet concerned as on the offspring.
There is no “carrier” in dominant mutations, for the simple reason that the carrier will have the mutation that will be visible, and will take place in front of the recessive mutation.
mutation A recessive mutation means that on the pair of chromosomes, it is imperative that both chromosomes are “carriers” of the same mutation for it to be physically expressed on the parakeet.
For example, two parakeets are mated each homozygous (the same character of the mutation on each chromosome (the pair), or vulgarly called “purebred”. One is blue (recessive mutation), and the other is “wild” green (dominant mutation). We obtain a generation of young who will all be of the “green” type (in the physical aspect) but they will each be carriers of the blue mutation (recessive). So they will be green parakeets carrying blue. Now let’s take a blue carrier green couple and mate them. We will obtain a generation of homozygous green Budgie (25%), blue carrier green parruchons (50%), and finally blue budgie (homozygous, 25%).
couple Blue carrier green couple:
The green mutation
The blue mutation
The gray mutation
The purple factor
On a wavy parakeet with a white base without this dark factor, we will speak of “purple blue”, which will have purple reflections distributed unevenly on the body.
It will be considered that the mask extends to the entire head and the characteristic ripples are less extensive. The opaline mutation causes a decrease in melanin in certain parts of the body. The mutation forms an absent V of ripples on the upper back after the neck. In addition, the black beads of the mask are well-defined and larger. Sometimes they can form a Beaded necklace.
Light wing mutation
Wavy parakeets carrying the “light wing” mutation will have yellow or white wings with feathers (long wing feathers) that appear light grey. Other writers (central retries, the top of the wings) are of a more normal color, that of the body. Ear spots are purple. Finally, the tone of the body color is barely lighter than if the parakeet were not a carrier of the mutation light wings, unlike wings that are well diluted, as well as the neck and head.
Grey wings Mutation
Iace wings or lacewing mutation
The lacewing mutation is related to sex and appeared in 1940 in England. The mutation causes a partial withdrawal of melanin in the plumage. The lacewing changes the design and natural colors of the wing feathers and leaves a central core composed of diluted melanin to brown color. This gives the appearance of relief, slight curves, discontinuous and symmetrical, brown in color, like lace. The eyes are red and the wax of the masks is pink.
The spangles mutation
The yellow-faces mutation
Yellow mask type I (MJI)
Yellow mask on face and secondary effects
Yellow mask type II (MJII)
Very bright and generalized yellow mask on the wings and on the body
The Danish Pie mutation (recessive feet)
The Danish magpie mutation causes an absence of the eye circle and the eyes are black. The basic color is found on the lower half of the body, the remains of melanin being distributed irregularly on the back, wings, and neck which impacts the distribution of feather color and undulations. The wax is normal in the female but it is purplish pink in the male (pictured above). Finally, the spots are present from 1 to 6 instead of 6.
The Australian Pie mutation (dominant feet)
The Dutch Pie mutation and Clearflight and Clear body
Light penne parakeets are predominantly heredity: only the seven primary feathers and large tail feathers are clear and this is added to a light spot behind the neck. Thus a pale pennies wavy parakeet has feathers and clear retorts.
The Dutch magpie mutation is characterized by the color of the mask (which is the base color) that goes down quite low on the chest. Dutch magpies also have feathers and the bottom of the wings light, as well as the characteristic spot at the back of the head As with Australian magpies, the double factors Dutch magpies are almost entirely devoid of ripples.
The Ardulate Mutation (Slate)
The Cremino or Ivory mutation
