Small practical software allowing to have the probabilities of the results of a mating according to the mutation (s) of the respective parents. It can be put on USB sticks, no need for an internet connection to use it.

Before that, we will obviously need to know the genotype of each parent. To help you determine the mutation or combination of mutations to which your zebrafinch belong, you can refer to: Illustrated glossary of mutations in zebrafinch.
That said, I would say that this application is only an aid. The best thing will always be to understand how each mutation is transmitted. For this, I also advise you to have a good basis to consult the article: Zebrafinch genetics : Instructions.

Here is a site, also available in application, dedicated to the calculation of the genetics of zebrafinch. ZebraCalc allows you to have the probabilities of results depending on the mutations of the respective parents.

Before that, we will obviously need to know the genotype of each parent. To help you determine the mutation or combination of mutations to which your zebrafinch belong, you can refer to: Illustrated glossary of mutations in zebrafinch.
That said, I would say that this application is only an aid. The best thing will always be to understand how each mutation is transmitted. For this, I also advise you to have a good basis to consult the article: Zebrafinch genetics : Instructions.

Genetic transmission of physical characteristics

If you ask at a meeting of zebrafinch lovers a question about the genealogy of the masked, the pastel, or a black cheek, you are sure to receive the right answer.
But if we ask the genealogy question about the format (size), the shape of the head or the length of the beak, the answers will be multiple and different.
Some will say intermediaries, others dominant, etc.

Nevertheless, these characteristics follow Laws of Mendel. Many breeders do not believe this explanation, but it is true. It seems that the laws no longer behave in a strict way as for the mutations of colours. A wider variation in the format (size), shape of the head, etc... seems normal.

Law of independent assortment

In nature, zebrafinch have the same variation in size. And, in the process of domestication, this difference in variation has increased. Our cultivated zebrafinch are on average two centimetres wider than their ancestors in nature.
In the articles, we always recommend a hard selection at the level of format and model taking into account the differences between the parts such as the head, the body, etc.

But the format and the model are driven by genealogy. The body shapes are driven by factors.
The question that arises is: Is there a relationship between the different factors that govern the format, the model, the shape of the head and the beak ?

Ring your zebrafinch

1. Benefits of ringing your zebrafinch

This will allow you to know their year of birth and to identify them, which will be essential for establishing a genealogy and monitoring your breeding. Each ring will be the identity card of each of your zebrafinch.
In addition, if you wish to have one of your zebra finches compete, only those who are ringed can participate. The ringed zebra finches of the current and previous year are eligible to participate in a gathering.
Then, a breeder will always prefer to buy a ringed zebrafinch on which he can be sure of the year of birth of this one and be informed of its origin.

How to create a strain according to its objectives

1. Define your objectives

First, in my opinion, it is necessary to target and define its objectives: Choice of mutation (s) to be selected, studies of the characteristics of the chosen mutation (s), knowledge of the type of genetic transmission, creating a network of breeder likely to work on similar objectives to have starting subjects. The breeders will need to have confidence in your project and your insight. They will also be concerned about the fate of their surrendered birds.
Essential conditions to then start the construction of a strain and start a selection in order to tend towards your defined objectives like any project.

Finally, define your idea of the bird you want to get. Without forgetting the characteristics of the mutation or combination in which you are projecting yourself.

2. Tips for getting started

Choose the starting zebrafinch with the fewest possible flaws. Be especially careful not to start with birds of uncertain genotype.
Example: If you have a project to build a strain of gray, check if they would not carry a mutation with recessive inheritance (like black chest, black cheeks).

Ask the breeder giving you your first specimens, ask to see the parents to be better fixed. Observe the different qualities and areas for improvement of each one, keeping in mind the zebra finch you want to achieve.
Observe the harmony and the whole of the birds of the breeder, a homogeneity will make you appear a good work of the breeder.

3. What is a strain

You have to imagine the stump of a tree, its trunk and its branches, made up of ancestors, descendants, sisters, brothers, etc. Different methods exist depending on the type of genetic inheritance of the mutation or high combination to advance a strain.
