The mutations of the zebra finch in photos ! Overview of free sex-linked, dominant and recessive mutations. Example of mutation combinations.
This article is based solely on the phenotype (visual traits) of each mutation.
To identify the genotype (genetic characteristics) of your zebra finch, it will be necessary to take into account that it can carry certain mutations without being a mutant.
Being a carrier (/) of a mutation means that it is partially present (genetically speaking). From a visual point of view the partially carried mutation will not be seen or only by some clues present in the appearance of the bird.
In this case, it will be necessary to have a trained eye to determine the genotype. Sometimes verification couplings will be necessary.
Your zebra finch can also have several mutations, the possible combinations are numerous.
The gray zebrafinch is not a mutation, it is the original (wild) type.
1. Gender-related mutations
The female can never be a split, so she is either mutant or non-mutant.
The male can be a split of the mutation.
Mask, old type
Mask, new type
2. Dominant mutations
Neither male nor female can be a split, it only takes one mutant to obtain 50% of young mutants.
Black face (BF)
3. Free recessive mutations
Both male and female can carry the mutation. The trait must be present twice to be visible in both male and female.
4. Some combinations of mutations
Male black face, orange chest, black chest
Male black face, black cheeks
Male mask black cheeks
Pastel male pale back
Female brown cheeks
5. Uncommon mutation
