HELP with lacing inheritence

[Victor_q]

This is kind of a continuation of a thread I posted years ago involving a lavender oegb x a silver sebright rooster in attempt to create a lavender laced rooster. I’ve made progress and my first lavender laced chick has been born. This is my second batch of chicks that have hatched from the parents this year all those chicks are bigger now and I’ve included photos. A single chick survived from the previous clutch and it’s lavender but how can I tell if it has any lacing genes ?

My question is, is it possible for a chick to be split laced ? I’ve heard that for lacing to occur it’s best, it needs to copies. But how can I tell if a bird is heterozygous for lacing ?

With these lavender chicks there doesn’t seem to be any patterning
And with the previous clutch all the chicks that had a “chipmunk pattern” grew to be laced

Photo 1 : lavender laced chick. Lacing is evident because of the “chipmunk pattern” with white and lav

Photo 2: it’s sibling

Photo 3: first clutch this season from the f1 x f1 cross

Please feel free to ask questions and TIA for any help

If a bird is heterozygous for the lacing gene it will still be sort of laced but the lacing will be poorer.

Oh okay. So these fully lav chicks (unless they show pattern when they’re grown) have zero way of passing on the lacing gene ?

When they are fully grown they may have some lacing.
It’s just that black (lavender is just the lavender gene on a black base) is very dominant, so these birds will be predominantly lavender. However, the lacing genes may still be there and they can have laced offspring.

Oh, by the way, these chicks are the second generation, right?
If so, there is a chance they have the genes for lacing and a chance they don’t.
If this is the first generation cross it is impossible to get lavender chicks, they would be black.

Yep second generation, they’re parents were all black with some small white details and the only one that showed any kind of leakage was a rooster with gold/yellow hackles which was expected

Curious to see how they feathered out. Any updates?
