Self Blue (Lavender) Silkie Thread

Ok, it's to early for my brain to be working correctly so I have a question that may be clear but not to me this morning.

So lets say you breed this blue hen to a black rooster. You will get 50% black and 50% blue.
Question is will some of these chicks (50%) still carry one of the lavender genes and be lavender splits or do you lose that since dad was a pure black?

Ok now you breed one of the black male (if it carries the lavender gene) offspring back to Mom You would get your lavenders.

Yes? No?

Hmm, I don't know.

I think if I bred to a black male, I would get 50/50 blue/black, not sure how diluted the lavender gene would be! Instead of being 50% split to lav would the chicks be 25% split to lav?

Okay, you are talking two separate genes here: lavender (lav) and blue (Bl). Rather than saying "black" let's say "not-lavender" and "not-blue."

If both are pure for not-lavender, then offspring will be about half black and half blue and all will be pure for not-lavender.

If one parent (either one, doesn't matter which) has one copy of lav, then about half the offspring will inherit lavender and the other half will inherit not-lavender. With large enough numbers, statistically this will work out to about half of the blue chicks and about half the black ones. But that requires MANY, MANY chicks. Anything less than several hundred (check the chicken calculator for numbers) is unlikely to be evenly balanced.

If both parents have one copy of lav, then about a quarter of the chicks will inherit two copies of lavender; another quarter will inherit two copies of not-lavender and the remaining half will inherit one copy of lavender and one of not lavender. If the lavender chicks inherit one copy of blue, you can call them lavender blue; if they inherit two copies of blue, call them lavender splash; if they inherit two copies of not-blue, call them lavender. Now your bggest problem here is distinguishing between the birds that are blue or splash AND lavender and the ones who are blue or splash AND not-lavender. Almost impossible to distinguish by appearance. Only the lavenders who are pure for not-blue are easy to distinguish. And if you are not expecting them, one might simply think that they are just a light blue, not realizong that they are lavender.

I love this stuff!

Thank you, Sonoran, for explaining this. I have read what you wrote about 20 times trying to absorb it!

Is the gene for splash (blue) dominant over lavender in how it expresses physically? So if I breed my blue split girl to a pure lavender rooster, and some of the offspring inherit two copies of lav, they will still be phenotypically blue?

Thank you!!
