Color genetics thread.

this is I pic of the parents....and below 2 pics of the pullets with the recessive phenotype 1 with white legs( dirty legs) and the other with blue legs..

What do the males look like that are produced from the cross?

 

[llalo8524]

they all look like there father light red black breast white legs.

My best guess is that the hen is carrying dominant wheaten and an allele that is recessive to the dominant wheaten- either recessive wheaten or the brown allele. I believe it to be the brown allele. She is also carrying one dark brown gene. The hen is also carrying a melanotic or some other black iintensifier.

The male is dominant wheaten and also carries a recessive allele- recessive wheaten or brown

The minority offspring are a combination of the two recessive E locus alleles (brown/brown or brown/recessive wheaten),they carry a single copy of the dark brown gene Db*Db / Db*db and the black intensifier (melanotic). One of the parents is carrying a single copy the pattern gene. Could be either parent- most likely the hen.

The rooster also carries one copy of dermal melanin; this is why some of the pullets have blue shanks.

the dirtty white legs are due to the brown E locus allele. Most of the time dirty shanks is due to birchen but the only other recessive E locus alelle that adds color to the shanks is the brown allele. This color is normally horn in color.

Over on the Ameraucana thread they said the offspring from two different color true Ameraucana would result in offspring of a non-standard color because of the slightly different backgrounds involved in creating the color variations. They'd be Ameraucanas, but since the color is non standard they'd have to be called easter eggers.
Now, the lady I got my chickens from did have an Ameraucana hen in the coop with her Marans hens and the rooster in that coop (according to her) is a blue Ameraucana. I managed to find a picture of him from last year on the lady's facebook page, but he looks splash to me.

Here is my Sassy's father and Sassy. Could a crossing of that male + another Ameraucana of a different color create Sassy? either way (yes or no) could you please explain to my why? Thanks.

I do not think she is the offspring of the rooster. Normally the offspring of a blue/black/splash crossing with another variety produces blue/black/splash offspring. With that said, it is possible that she is the product of the cross. Do you have a picture of her as a chick. Down color is very helpful in determining certain genes that are in the bird,


Sassy carries blue, autosomal red, mahogany, silver,dark brown along with columbian , one pattern gene and an E locus allele that is not extended black most likely wild type/brown heterozygote . One of the parents was black tailed red or self red phenotype (like a rhode island red, buckeye, villafranquina)
In this case, it was a speckled sussex.

My reasoning

Lacing on the breast and autosomal barring are associated with the dark brown gene in combination with the pattern gene I went with brown as the other allele because some self red birds are this genotype (like the sussex). I did not go with wheaten because wheaten suppresses the production of black pigments,

She is sex linked silver because her hackles are silver- she does not carry melanotic because her hackles and head have too much silver in them

She is restricted (very little black on the back and breast)- this is due to the dark brown gene- the dark brown gene is a powerful columbian like restrictor that in combination with columbian removes black from the tail (she has red in the tail) - dark brown is also associated with autosomal barring ( some in her wings) and lacing on the breast The lacing on the breast is not black because the blue gene is diluting the black.

the dark red color is due to the mahogany gene and autosomal red- she should be silver in the red areas but the autosomal red and mahogany cover the silver.

the splash father would have contributed the sex-linked silver, wild type allele and the pattern gene- genetic blacks often carry the patterrn gene.

@Wappoke

wow, thank you so much for all of that wonderful information. I'll have to read it a couple times to absorb it all.
Here is Sassy as a chick....

the striped one is Sassy less than 1 week



close to 2 weeks



three weeks old.... sassy on the top-left
The one on the right is the black headed pullet I asked about earlier.
The middle one is much less detailed than Sassy, more like the Gray except without the black head.

 

[Chicken5555]

you mentioned the birchen gene, could Sassy's mother be a birchen marans, or a black-copper marans? The lady who owns the parents has a lot of different marans chickens. She also has speckled sussex.

Her chick down color indicates she is not birchen but brown/wild type at the E locus. I will have to go back and rethink the genetics.

I believe the speckled sussex is a parent- that is where the restrictors, mahogany and autosomal red came from.

I look forward to your analysis.

I have a Blue Cochin and was wondering if I got a Partridge Cochin hen, would chicks look similar to this?
