Is this a self-blue/lavender or a splash? Your opinion please!

[Three Cedars Silkies]

Alison,

Assuming this is a splash and not a self-blue, what do you think you would get? The person from whom I got the eggs said that they do use splash in developing the lemon blue coloring, so I'm fairly certain this is a splash. He did encourage me to breed this splash back to a lemon blue. I think I'm definitely going to do this. God only knows what we'll get!!

It appears to have some darker feathers in a few areas which means it would be splash. Lavender or Self Blue all the feathers will be the same shade, no variations.

A splash to a self blue will get you black.

I don't believe you will get a black. I believe you will get lavender split blues. Not sure though, I am certainly no expert. I agree with Jody. Trying to breed to a BBS group would be too messy.

Okay, I need someone who can settle/explain this. I've gone over to my favorite genetics site and am still confused, because I think the gene for lav is carried at a different site than the genes for black/blue/splash, so.....beginner that I am, I need someone to do the Punnet Square thing on this one for me.....puleeze..... Calling on the genetic gurus !!!!!

Susan,

Here are some things to remember about the lavender gene and the blue gene. Both the blue and the lavender gene are genes that dilute black pigment. So in order to have a ( solid color) blue, splash or (self blue)lavender bird the chicken must first be a completely black bird. You can think of it as if a black bird is under the blue, splash or lavender bird.

The lavender gene is recessive which means it takes two of the lavender genes to make a lavender ( self blue ) bird. The lavender gene will also dilute red pigment so if a person breeds two lavender genes into rhode island red, then the person will have cream/buff colored birds with lavender tails and some lavender in the wings. I would love to see that.


The blue gene is incompletely dominant this means that one blue gene will produce a color different than two blue genes. One blue gene produces a blue bird while two blue genes produces a splash bird.


Crossing possibilities

black to blue = black and blue

black to splash= all blue

black to lavender = black

black ( split or heterozygous for lavender) to black= black

black ( split or heterozygous for lavender) to lavender = lavender and black

black ( split or heterozygous for lavender) to black ( split or heterozygous for lavender)= black and lavender

blue to lavender= black and blue

blue (split or heterozygous for lavender) to lavender = black, blue and lavender ( you could get birds that are blue and lavender)


blue to blue = black, blue and splash

blue (split or heterozygous for lavender) to blue (split or heterozygous for lavender)= blue, black, splash, and lavender (you could get birds that are blue and lavender or splash and lavender)

This is an interesting cross and would produce a ratio of 6 blue :3 black : 3 splash : 1 lavender : 2 blue and lavender: 1 splash and lavender)

blue to splash= splash and blue


blue (split or heterozygous for lavender) to splash= splash and blue


blue (split or heterozygous for lavender) to splash(split or heterozygous for lavender) = splash, blue, splash/lavender and blue/lavender

I may have missed a few possibilities but I think I have most of them.

Okay, Tim, that's just exactly what I hadn't quite gotten before: that lavender and blue are both modifiers of black, one recessive and one incompletely dominant...

And, with what you have given me, when/if I put my mind to it, I should probably be able to answer the original question, but....indulge me and tell me what the result of a cross between the lavender and the splash would be.

I'll go and drink my morning cup of tea and see if I can figure it out and then come back here in a while and see if I got it right.

This is like having a private tutor in genetics.....Thanks

So now that I think of it... If you breed a splash to a lavender, you'd get... a blue! Right? Because The lavender would give the offspring one set of lavender genes, which isn't enough to show up, so it'd pretty much be like breeding a black to a splash, which would get you blue.

Whoopeeeeeee.
Thanks Tim and Madison.

I hadn't gotten there myself, but now that I have the answer and the reasons for the answer, it adds to the likelihood that I will get it.....next time.

I have an RIR - now I'm gonna have to find me a lavender bird to breed with it - if it ever decides whether its a pullet or roo...

 

[quilter28634]

I have a genetic question for the genetic guru please: If I breed my Black split Lavender Rooster to a 'silver' white hen, what would be the possible outcome colors. And I thank you very much for the answer. I see the other colors mentioned on the thread, but no one has mentioned breeding white hens to colors yet and I am curious.
