will black rosecombs and white rosecombs give me blue rosecombs ?

[nzpouter]

rust or yellowy silver?

 

[Poulets De Cajun]

rust... its copper/red in color. but its very faint, an only in the upper wing area.

I did it as a last year for science project. And i told some that i did it and he told me that itvis blue rosecomb.I have one grey one out there.

lavender act as dilution, so any pattern/ colour you have will be greatly reduced in intensity, black to blue, red to yellow, etc.

Yup, it sure will. I've done this cross twice now and gotten quite a few laced and non laced blues each time.

It won't give you blue 100% of the time as it depends on the genetic makeup of your whites. With mine I got mostly blues with a few blacks mixed in.

White in rosecombs tends to be recessive white on a separate allele than the color gene. In other words you need two copies of the white gene in order to 'cover up' the base color of the birds. The bird still carries color genes, but does not express that color. Sort of like throwing a white sheet over a colored birds. There is still color present, but you can't see it because of the sheet covering it.

If the bird only has one copy of the white gene then it will show color, but will be able to produce white under the correct circumstances. If you cross a colored bird that carries one copy of the white gene with a white rosecomb you will get approximately 50% white chicks. If you cross two birds that carrie one copy of the white gene, then approximately 25% of your chicks will be white.

This rooster here is a black/white cross:

These two are also black/white crosses:

These white hens are the product of the blue/blue mating with the birds that carried the white gene.

see? whatdiditellya!

breeding and genetics as almost unpredictable. but just because coyote got pretty blues/grey doesn't mean it's going to happen all the time. genes aren't guaranteed.

in many cases, florists will cross pollinate red roses and white roses to create pink. this is how the majority of pink roses come around. genetics are certainly not 100% predictable in what turns out, but it can be said that you can make an educated guess.

i spent my high school years working with tomatoes, (i was an intern at UAF) and we ended up with a strain of tomatoes with only 2-4 seeds. It was a small project, and that strain no longer exists (we ate them).we also spent some time with flowers and moths.

through breeding, keeping track of family trees And throwing in random genes can eventually give you outstanding results, given you have enough time. to get a really great blue, it may take one try, it may take several years, or you may never get it. but that's the joy of it! you may unintentionally create a bird that is not what you were trying for, but turns out STUNNING!

this is why i love keeping chickens. i like to do little cross-experiments, selective breeding and looking for who has what genes. it truly is a wonderful experience!

Actually, yes you will get blue. http://www.rosecombs.ca/rose_breed.html

edited to say: Urban Coyote beat me to it

Urban Coyote, you are a member of the Canadian Rosecomb Federation aren't you?

 

[Black Feather]

Yup, I'm a member of the Rosecomb Federation

I don't think there's a Canadian one, just a worldwide organization.

I think it sort of makes sense that when you cross black to white rosecombs that you get colored birds in the black, blue and splash lines. For the longest time you would only see rosecombs in black, white, blue and splash....so it would make sense that most of the crossing between the colors would be within those boundaries. Now that there are more colors floating around you may see more mixing within the white lines that would create some interesting outcrosses. I'm not sure about this of course, just an educated guess.
