Sex- linked Information

[Ridgerunner]

No. If you carefully read the first post in this thread, you will see there are three basic ways to make a sex linked chick. In all three methods, the parents have to have specific genes with the father and specific genes with the mother. You don't have that.

Thank you, I read it but am unfamiliar with the terminology.

Briefly, to make a red sex link, the rooster has to have a gold gene, which means he is probably red, and the hen has to have the silver gene. The hen is a bit more tricky because she probably has some white feathers, but not all white hens have silver. And not all hens with silver are predominantly white, Silver Laced Wyandotte, for example. The male chicks from this cross will be yellow and the female chicks will be reddish. With some specific breeds and crosses, the difference in yellow and red can be a little hard to see.

To make a black sex link, which are not necessarily black, the rooster can be a lot of different things as long as he is not barred, and the hen has to be barred. The male opffspring will have a white spot on their head and the female will not have this spot. Where this can get tricky, the rooster and hen have to be colors that the white spot can be seen on the chick. That's why blacks are usually used as part of this. You can use blue of red for the chick color, but the spot is not always real easy to see. Even on some partial blacks, it can get tricky.

With feather-sexing, the father has to be have the fast feathering gene and the hen has to have the dominant slow feathering gene.

What makes this work is that genes normally come in pairs. The rooster is generous and gives one of all his gene pairs to all his offspring. The hen is sexist and stingy. There are a few specific genes she has that are not paired but she only has a single copy. She only gives a copy of her single genes to her sons and she short-changes her daughters. If the genes the hen gives to her sons are dominant over the genes the rooster gives to both his sons and daughters, and those differences can be seen at hatch, then the chicks can be sexed at hatch.

For example, barred is dominant over not barred. If the hen is barred, she gives a barred gene to her sons but not her daughters. If the rooster is not barred, he gives a not barred ot both his sons and daughters. So the daughters get a not barred from their father and nothing from their stingy sexist mother and the pullets are not barred. But the roosters get a barred from their Mommy and a not barred from their Daddy so they have one of each. Since barred is dominant, the roosters will show barring.

Since your Cuckoo Maran rooster is barred, he will indescriminately give a barred gene to all his children, so both male and female offspring will be barred regardless of whether the hen is barred or not. You will not be able to tell the sex of your chicks at hatch by the barring.

I don't know if this is any simpler or easier to understand. But it all works because the hen is sexist and stingy with a few of her genes.

Sorry if this has been brought up before but will a Cuckoo Maran rooster over average color EE's produce a sex-link chick?

no.. but a cuckoo maran Hen mated to any EE(not another cuckoo or barred) will produce sexlinks...

you forgot about sex linked id+ and Id genes.. this can also be used to sex link birds...

THe cuckoo coloring needs to be in the hen, not the rooster. THen you can use a rooster that will allow the black coloring from the hen to show thru. Most of the EE don't breed true IMO, so you would need to run trials to find out which EE rooster to use. Review the charts in Post #1 for suggestions. GL

Thank you, I read it but am unfamiliar with the terminology.

Do not read it like a novel- you have to read it slowly and multiple times. Get familiar with the terminology. A little education goes a long way.

I have some education in genetics and still the first post is a challenge . Really, the biggest challenge is in the specific breeds and there is no way to list every breed.

OMG!! This thread is still "alive"??????
