Blue/black/splash genes

No they were Splash, trust me I know a splash when I have one. I'm not new at this, but I believe that they were related very close, so that would allow the genes to come out.

some breed black to white its not that uncommon, just depends on what the goals are..

however i think if breeding a dominate white to splash you will get a % of white off spring, but not sure of the other % from that crossing, not sure how a kip would answer, as i never attempted to see what would be the results using the kips..

My point is that there are so many people that are new to breeding/genetics. That they read what others post and believe it as exact. Not realizing to get thess ratios they would have to breed 100 birds, not 12.
This square is not and exact, that there are other factors involved, and people who post this should add a warning when doing so for those newbies.

Blue x Blue = 50% blue 25% Black 25% Splash
Blue x Black = 50% Blue 50% Black
Black x Splash= 100% Blue
Splash x Splash= 100% Splash
Black x Black = 100% Black

No, splash x splash = splash

WRONG!!! I've had this happen before. I had a set of Splash silkies in a pen to gether and ever other egg that the hen layed was a white silkie. They were the only two in that cage for 1 year. So just because it lloks good on paper, nature has her own plans!​

Each of your birds carries one copy of recessive white. So 25% inherit a copy from each parent and thus are white. There is no way to tell which of their offspring (another 25%) do not carry it versus the 50% who inherited only one copy. Recessive white is an OFF switch, preventing the formation of feather pigment.

If you pair these birds with different mates, you will eliminate the white offspring (assuming the new bird does not carry recessive white). However, about 50% of the offspring will have a copy of recessive white.

My point exactly, you can quote the science books all day, but people are getting birds in one color,not knowing their background breeding. They breed 2 birds together, expect them to bredd"true" and when they get a different result are totally confused. So I would like to say, if people want to but on the Blue x Blue = Blue ie that they also state that this is a theory, that nature always has a plan. I received Balck silkies from a Master breeder once that had 15 gens of black breedings and guess what he hatched out, you got it a white! So nature is not an exact science that is why you get a genetic mutation once in awhile!

I will heartedly disagree that nature is not an exact science. Our understanding can certainly be inexact or incomplete. The white chick from this black breeding comes from the same explanation as I just made for your splashXsplash=white. The difference in numbers is that with your splash, as you said, it was a single pair; in this case you there was probably only one hen who carried recessive white (plus the cock, of course). This was not a mutation; it was a case of recessives from each parent pairing up.​

"These only work If the colors are true, no hidden genes bred in the background"

There is no way to tell if a bird has hidden genes; as you have shown, they can hide for generations. I would speculate that far more birds have hidden recessives than do not.

It is periodically mentioned that these are statements of probability, which means that a more accurate statement is that each offspring has a 25% chance of being ___, 50% of being ____, 25% of being ___. (or 50/50 in those cases). With large numbers these percentages tend to match the population, but just as the result of a 2nd coin toss is not predicated by the result of the previous toss, the result of one egg has no bearing on the result of a different egg from the same parents.​

Chick down is indicative of the genes present, but there are a number of chick down patterns that are pretty similar.

They certainly can; these are unrelated genes.

Hi,
Which is the Rooster and which is the hen? Or does it even matter. Is the code always:- Rooster color X Hen color = % ?
Thanks.

In this case, which is which makes no difference; with sex-linked varieties it does.

Nomenclature is usually Cock X Hen.
