Simplified run on the genetics:

Introduction to the genetics:

In the genetics and the study of heredity. We notes various modes of transmission of the characters of the parents.

On this page of Canaris Pleasures, you will find the various applications of the latter on canariculture.

The genetics is based first of all on the quality of observation of the male and female individuals. On their at the same time morphological and physiological characters: all that this sees with the naked eye calls the phenotype.

The genotype of an individual is made up then of the phenotype of the individual him even and the phenotype of its descendants (not visible characters).

Thanks to the practice of many breeders in the genetics. The colors in the canary multiplied with the wire of time.

With force of multiple crossings and tests on behalf of the breeders of the whole world of new colors as Onyx appear each year during the exposures and contests.

Bases of the genetics:

As everyone knows it. The smallest alive unit is the cell, any individual is composed of different cells. The units tranmises from generation to generation are called genes, several genes constitute the chromosomes. The genes are along a giant molecule that the ADN is called and the chromosomes are located in the cores of the cells. Sometimes a modification of the central molecule can intervene, which gives a transfer, the transfer then involves a notable change of the aspect of the children compared to the parents. A gene can be to modify into two or several forms called alleles or allelic forms.

Genes and chromosomes

A gene occupies a particular site along a chromosome. This site is called the locus (loci in the plural), allallelic shapes of a gene are then on similar zones on equivalent chromosomes. All the genes carried by a same chromosome are bound, it is what is called the linkage.

The chromosomes at individuals are divided into two parts. Those coming from the father and those coming from the mother (each batch from chromosome provided by a relative is called the ploïdie). The genome is the whole of genes carried by a cell, the number of chromosomes of a somatic cell is identical for all the individuals of a same species. In the birds, the number of chromosomes is 80 pairs including 9 pairs of macrochromosomes.

Various factors can play in the genotype of the young canaries : carriers, sex of the parents…

But in order to simplify all these things which can appear to you a little complex, some diagrams in order to help you here to carry out the best couplings with your canaries:

First example : The Inos canaries

Parental lines:

Ino X Not-Ino = 100 % Not-Ino F1

Form 1 between them (F1) :

Not-Ino X Not-Ino = 1 Ino for 3 Not-Ino

Crossings between Form 1 and Parents:

Not-Ino (F1) X Not-Ino (Parent) = 100 % Not-Ino

Not-Ino (F1) X Ino (Parent) = 50 % Not-Ino et 50 % Ino

Second exemple : The Red and Yellow canaries

Third exemple : The Pastel canaris

Fourth exemple : The Satin canaries

Fifth exemple : The Ivories canaries

Of course it is impossible for me to describe you all the possible crossings.If you have any questions about other crossings do not hesitate to contact me either by mail. Or using the forum of the site. Good tests and good surfing on Canaris Pleasures.
