Crossing laced polish

[M_coosae]

So can anyone confirm whether polish can be sex linked?internet seems to be conflicting. If I cross a silver laced rooster with a gold laced hen, will all my gold laced chicks be roosters? Based on what I am seeing this seems to be a breed specific phenomenon. Thanks in advance

Silver rooster over gold hen makes silver females and lemon males--You probably won't be able to tell them apart until they mature.

Gold rooster over silver hen makes gold females and lemon males, and you should definitely see a difference.

EDT: this applies to any gold/silver chickens. That's how ISAs and other sexlinks are made.

Well that's interesting because I can easily discern between gold and silver pretty much at the hatch. And no doubt by 1 week

@sylviethecochin is correct. You won't get any gold laced birds from this pairing; females will be pure silver laced polish (S/-), males will be mixed-colour silver and gold (S/s+).

For a sex-linked cross, aka gold females (s+/-) and mixed colour silver and gold males, which can be sexed at hatch through down colour (females will appear reddish, males yellowish), you would need to use a Gold cockerel over Silver hens; this works as males have two 'slots' for gold & silver genes whilst hens only have one, so hens can only pass their colour (in this case silver) onto their sons; Silver is dominant over gold, so females will be pure gold-laced polish and males will be mixed colour silver and gold.

I don't believe they will be sex linked at hatch. They will be "sex linked" as they feather out. The pullets will be gold laced and the cockerels will be yellow/gold laced. Yellow/gold laced and lemon are the same. You say Tomato... I say heartburn.

Lemon males look {EDT: mostly} silver. Silver is incompletely dominant. That is a Silver/gold ISA, below. As chicks, they look nearly white

What does incompletely dominant mean. Isn't this an oxymoron. I've heard of dominant genes. Correct me if I am wrong but, isn't it impossible to get a silver laced from a gold laced x silver laced cross?

Incompletely dominant is like co-dominant, but one [EDT: allele] has more influence than the other.

Took me a bit, but I found a good link

Exactly this; in chick down, you'll see yellow, like a silver chick, but as it grows you'll start to see that cream colour coming in, showing it has both genes. Only cockerels can have both, females have to be either silver or gold, and get their gene from their father. Therefore, if the father is silver and the mother is gold, all the pullets will be silver and all the cockerels will be both silver and gold. If the father is gold, and the mother is silver, all the pullets will be gold, and the cockerels will be both silver and gold. If the father is silver and gold, then the girls can be either, but they have to be one or the other.

Well my laced birds must have been crossed in this fashion previously. Because my 4 week olds are gold not lemon. Will post pics some time so it can be confirmed
