Green opaline paired with violet fisheri.

When breeding a Green Opaline Fischer's Lovebird with a Violet Fischer's Lovebird, the resulting offspring will exhibit a range of colors and traits based on the genetic makeup of both parents. Here’s a detailed breakdown of the potential outcomes:

1. Coloration and Mutations:

Green (Wild-Type):

The green coloration is dominant, so many offspring will likely have a green base color.

Opaline:

The opaline mutation is recessive and causes a dilution of body color and more vibrant feathers on the back and wings. Offspring need to inherit the opaline gene from both parents to exhibit this trait.

Violet:

The violet mutation is a semi-dominant trait that enhances the intensity of the blue coloration. This mutation needs to be present in either a single (SF, single factor) or double factor (DF, double factor) form to express violet coloration. Single factor violet will show a lighter violet hue, while double factor will be a more intense violet.

2. Genetic Scenarios:

Case 1:

Green Opaline × Single Factor Violet Fischer’s

Offspring Colors:

- Green (with some carrying the opaline and violet genes)

- Green Violet (if the violet gene is present in the single factor form)

- Green Opaline (if opaline is expressed and carrying the violet gene)

- Green Opaline Violet (if both opaline and violet traits are expressed)

Case 2:

Green Opaline × Double Factor Violet Fischer’s

Offspring Colors:

- Green (with some carrying the opaline and violet genes)

- Green Violet (more likely with double factor violet parent)

- Green Opaline (if opaline is expressed and carrying the violet gene)

- Green Opaline Violet (more intense violet coloration if double factor violet gene is present)

3. Breeding Outcomes:

1. Green Offspring:

- Dominant green coloration will result in many offspring being primarily green, especially if the opaline and violet genes are not both present.

2. Violet Offspring:

- Offspring will display violet hues if they inherit the violet gene. Single factor violet will show a lighter violet color, while double factor violet will be more intense.

3. Opaline Offspring:

- Opaline coloration occurs when both parents carry the opaline gene. If the Green Opaline parent carries it and the Violet parent does not, offspring will be split for opaline but won’t display it unless both parents carry the gene.

4. Violet Opaline Offspring:

- For offspring to be Violet Opaline, they must inherit both the opaline and violet genes. This outcome depends on the presence of these genes in both parents.

4. Possible Genetic Combinations:

Homozygous Dominant:

(e.g., Green/Green) – Green offspring.

Heterozygous:

(e.g., Green/Violet) – Green split for violet, some displaying violet if the gene is present.

Homozygous Recessive:

(e.g., Opaline/Opaline) – Opaline offspring if both parents carry the gene.

Semi-Dominant:

(e.g., Violet/SF Violet or DF Violet) – Violet offspring with varying intensity depending on whether the violet gene is single or double factor.

Example Genotypes:

1. Green Opaline Parent:

- Genotype: GreenOp (may or may not carry violet gene)

2. Violet Parent:

- Genotype: SF Violet or DF Violet

Offspring Genotype and Phenotype Ratios:

Green:

(Green/Green, Green/Violet) – Dominant green coloration.

Violet:

(SF Violet/Violet, DF Violet/Violet) – Violet coloration, intensity varies.

Green Opaline:

(GreenOp/GreenOp, GreenOp/Violet) – Green with opaline traits.

Green Opaline Violet:

(GreenOp/VioletOp) – Green with opaline and violet traits, intensity varies.

Conclusion:

Breeding a Green Opaline Fischer's Lovebird with a Violet Fischer's Lovebird will produce offspring with a mix of green, opaline, and violet traits. The exact distribution will depend on whether the violet gene is single or double factor and if both parents carry the opaline gene. For precise outcomes, knowledge of the genetic makeup of both parents is essential.
