cut throat finch genetic calculation

[sskmaestro]

Hi,

I am fairly new to cut throat finches. Last year, I got one pair of normal cut throats and one young pair of cinnamon cut throats. I didnt breed the cinnamons as they are young. But i bred the normals. Got normal babies.

This year, i got a new male bird, its yellow throat albino male. I have plans to pair this male with my cinnamon cut throat hen (red throat probably)

I searched internet to find the possible outcome for this pairing.

male : Yellow throat albino
female : cinnamon from red throat lines

what colored chicks will they produce and what mutations will they produce?

Appreciate the help in sharing the information.

Unfortunately he mutations you mentioned are either not available in Australia or very rare.

Is it possible that your cinnamons could also be referred to as Isabel.

If so the White, Isabel and Yellow throat are considered autosomal recessive, that is you can have birds of both sexes split for the mutation.

If the hen is Isabel only and the cock carrying only Yellow throat & White the I would expect all young to be normal in appearance but triple split.

I can only offer this as an educated guess. Hopefully someone of greater knowledge can offer a view.

Cinnamon and albino are both sexlinked mutations. So you might get albino hens or cinnamon hens but you can't split to either mutation in hens.
Cocks can be split to both mutations or be cinnamon split to albino or vice versa.

Just a quick note but a prominent US breeder sells guaranteed Split Albino Cutthroats hens.

I would suggest assuming an albino must be sexlinked is an error

Or the breeder does not know his genetics.
Maybe they are not Albino, but blackeyed whites?
Maybe they are double factor pieds and come out white?
All sorts of possibles.

here's the male. red eyes, yellow throat white bird and singing well.

He is definately a red eyed white. So Albino genetics apply.
But the hen?

Hen is a cinnamon mutation with red throat genetics

If a true cinnamon it is sexlinked recessive
