Color genetics thread.

the breast its almost gold just some black tips and the end of the feathers

if the females have black on the shanks then they carry birchen and the gold is due to sex linked gold, I would suggest they also carry melanotic and the dark brown gene and the pattern gene

they are not purebred for the genes so you are getting a quailish pattern- if they were purebred they would be autosomal barred

the quail plumage pattern is normally produced with wild type at the E locus

Is the wild type dominant or recessive to other E locus alleles?

thanks.... and its a ''trow back'' recesive phenotype ( just get 3 pullets with this color) because most of the stags and pullets of the clutch

look like his parents

OH WOW!!! you have stunning chickens. That rooster is amazing.

I agree he is gorgeous!

thanks just what to find out what gene the parents carry that will show i few pullets like this one clearly they carry something else.

It is amazing what is in the DNA mix, lurking in the parents... the more I read, study or stumble upon the more I realize just how complex it all is.

I was paying with the chicken genetics calculator and if I'm understanding correctly, one copy of the wild type gene gives the chicken a softer look and two copies causes the chicken to have well defined markings.
Like the difference between these two chickens that are sisters.....

order of dominance in predominant E locus alleles

wild type is recessive to extended black, birchen and dark wheaten and dominant to brown and light wheaten

Both birds in your pictures are of mixed genetic back grounds and have genes that are effecting the primary plumage pattern.

The E locus and sex linked silver locus determine the primary plumage color of a chicken

All the other genes act upon the plumage color produced by the E locus alleles and the sexlinked silver locus alleles


old english game bantams

birchen is actually silver allele plus the birchen allele
brown red is gold allele plus the birchen allele


wild type E locus plus sex-linked gold = gold duckwing females have salmon colored breasts

wild type plus sex-linked silver = silver duckwing females have a salmon colored breast

gold duckwing + sex linked barring gene(s) = crele

gold duckwing + dark brown genes = ginger

gold duckwing + one dominant white gene = red pyle

gold duckwing + mahogony genes + mottling genes= spangling ( actually mottling)

as you can see the E locus is a basic primary color pattern and other genes act upon the basic pattern to produce other color patterns

Extended black E locus plus melanotic = a black color pattern

Extended black E locus plus melanotic+ sex linked barring = barred

Extended black E locus plus melanotic + two mottling genes = mottled

etc.
