Color genetics thread.

[Potoooooooo]

Hinnies and mules are sterile, and the results of different species crossbreeding. Chickens are still chickens, regardless of breed. The roost is silver base color, carrying a gene for red. I'm assuming he inherited a barring gene. The mother is likely silver base color, no genes for red. I'm assuming she also inherited the barring gene. This means that any chick that hatches golden will be female. Also, any chick that does not develop barring is female. The rest of the chicks will be both silver and barred. Doesn't mean they are certainly males though, since the rooster has a copy of both those genes as well. The reason you get some sexlinking, is because he only has a single copy of each.

(Someone just found out how to quote ^^)
Oh yeah, I know they're sterile, but I meant it theoretically. (XD, still a TERRIBLE example, I realize)
I'm still really fascinated and marvelled by the genetic diversity of one bird.

Look at that chart! Despite both of us being //amateurs// with this genetic stuff, graphic designers always find a way to be creative, don't they?

It's interesting that that cross (whatever you choose to call it) produces an array of coloured chicks that can be female or male and sex-linked.

She appears to carry one blue allele- I agree she is blue. She can not be a sex-linked chocolate carrier because only males can carry sex-linked chocolate. This eliminates sex-linked chocolate. Her color is not correct for dun either or chocolate due to dun and modifiers. To get a chocolate bird with the dun allele- the bird has to have modifiers that produce some red pigments. The blue allele causes the pigments granules in the feather cells to be unevenly spaced within in the different parts of the feather and in some parts of the feather lacking. The shape of the granules are round and each feather cell will contain a loose arrangement of black granules. In black feathers cells, the rod-shaped granules are packed tightly inside the feather cells and found in every part of the feather. The expression of the blue allele is not the same in every feather and not the same in each bird. Some blues look almost like lavenders and others appear to be almost black. Evidently, there are genes that can modify the expression of the blue allele. (see pics below). If the breeder you purchased your birds from is producing blacks and blues they would breed birds that are only black or hypostatic black. Their should not be any birds that express red in their plumage. Where the red is coming from- could be a lack of black intensifiers in the bird you have. If you cross her with a lavender rooster, she will produce some blue and some black F1 offspring. Lavender is an autosomal (not sex-linked) recessive gene so in order for an offspring to express lavender, it must inherit one lavender gene from the mother and one lavender gene from the father. - all of the offspring will only inherit one lavender gene from the father. No lavender F1 offspring will be produced. This cross would be like crossing a black male with a blue female with respect to phenotype. Every offspring will be a carrier of the lavender gene so if you back cross the black F1 females to the male lavender parent- some of the BC1 offspring will be lavender and other BC1 offspring will be black. If you backcross a blue F1 female to the lavender male parent- the BC1 can be blue, black, lavender and mauve ( epistatic color due to the expression of both the blue allele and the lavender genes). Both of the birds below are blue but they differ in depth of color. This bird is different than the other two.

One more thought if she is homozygous for chocolate and heterozygous for blue could she have the blue appearance with some brown coloring?

I was wondering if anybody know what would the chick look like if I breed a buff Sussex rooster and a light Sussex hen together or if you breed a buff Sussex rooster with a speckled Sussex hen.

Buff rooster to Light hen would produce red sexlinks. Males will look like their mothers, and may develop some gold leakage as they mature. Pullets will be buff like their father.
Buff rooster to Speckled hen will produce chicks that are mostly Buff or red. Speckling is recessive.

this is what i got for buff roo and light sussex hen=

and I got this for the buff roo and speckled hen

(hope I helped!)

Thanks for responding everybody. What if the rooster was a speckled Sussex and the hens where light and buff. I only want to know because I only have one coop that is 100 square feet and I want to know if I can put the buff, speckled and light Sussex in the same cage or if I will need to get another coop. I was also wondering how many chickens I could put in a 100 square metre coop.

Speckled rooster to Light hens would still produce red sexlinks. Speckled rooster to Buff hens would have the same results as a Buff rooster to Speckled hens.
