Ok, so i know there are sex linked colours in lovebirds (meaning if your breed one colour with another the babies are sexed linked) i think they are fallow, and lutino (mabye australian cinnamon???), someone correct me if im wrong! ok so what i was wondering was that if you were to breed lutino peachface to a normal peachface would it be the daughters that are visual lutino and the sons split or the other way around??
sorry if this has been asked before:)

yay genetics my specialty! my time to shine!  lol if you pair a lutino cock to a normal hen all hens will be lutino, all cocks will be normal split lutino if you have a normal cock to a lutino hen all cocks will be split and hens will be normal hope that helps! |

Ok here is another one for you sam- or anyone else who knows:)
If both parents are spit lutino (if that can happen) would the offspring be sex linked also? or would the sex link skip their generation?

The term sex linked refers to the position of the mutation on the birds sex chromosome! Birds have two types of sex chromosomes, just like people do. In humans men are XY and women are XX, however in birds hens are XY and cocks are XX. Now, the Y chromosome is smaller and contains less information then the X. So, when a bird inherits an X chromosome with the lutino mutation on it and it is a female it will always be lutino because the smaller Y chromosome does not have enough information on it to override the lutino gene on the X chromosome. That means, hens can never be split for a sex linked mutation, they are either that mutation, or not. Cocks can have two X chromosomes, one with the sex linked gene on it and one with another gene on it. As sex linked genes are normally recessive, this means the other gene will mask the sex linked one. If a cock bird inherits two X chromosomes with the same sex linked gene on them he will also look like that colour.
I hope that was not too confusing. But in summary, you can not get a hen that is split lutino (or any other sex linked mutation).
So pairing a normal split lutino cock to a normal hen will give you 25% normal cocks, 25% normal split lutino cocks, 25% normal hens and 25% lutino hens.
Pairing a lutino cock over a normal hen will give you 50% normal split lutino cocks and 50% lutino hens.
Pairing a normal cock over a lutino hen will give you 50% normal split lutino cocks and 50% normal hens.
Pairing a normal split lutino cock over a lutino hen will give you 25% normal split lutino cocks, 25% lutino cocks, 25% lutino hens and 25% normal hens.
Hope this helps
