What Mix is this cutie?

[Chickens are awsome]

This is a 4.5-month-old chick that I hatched. I was wondering if you wonderful people on BYC could help me identify what mix s/he is. (Poll above has all possible mixes)
She also has Leg fluff.
(Sorry that the 1st one is kind of blurry she was moving alot)


Suspected parents ~

Roo is only rooster I had when she was hatched


Suspected mother Dominique ~

It's a cockerel. The mother has to have barring of some sort, and probably feathered legs since the father seems to have clean legs. She also likely has a single comb.

I second all of this. It is definitely male.

i probably don't need to say this, but yeah. it's a boy. not sure what breed, but he's beautiful!

his saddle feathers are outlined. he's about as boy as it gets.

Since the rooster is non-barred the barred youngster can only be out of a barred female and has to be male because that cross is sex-linked.

So what makes him sex-linked?

So what makes him sex-linked?

The gene for barring is on the Z-chromosome, which is the sex chromosome in chickens,

I'm on lunch at work and can't explain the details, but @NatJ or @nicalandia understand it better than I do.

So what makes him sex-linked?

Male chickens have sex chromosomes ZZ.
Female chickens have sex chromosomes ZW.
Barring is on the Z sex chromosome.
The W chromosome does not have any genes that we care about here.

Barring is a dominant gene, so a chicken cannot carry barring without showing it. Any chicken with the barring gene will have white bars on the feathers, although of course they are easier to see on some colors than others.

Your rooster has nice rich red and black colors, so it's easy to see he does not have white barring. Since he has no barring, he gives every chick a Z chromosome with no barring on it.
But the chick does have barring, so that must have come from the chick's mother.

A barred hen gives her sons a Z chromosome with barring, and she gives her daughters a W chromosome (that cannot carry barring.)
So a barred hen can only give barring to her sons, never to her daughters.

Since the chick did inherit barring from a barred mother, the chick must be a male.

Thank you for the very detailed explanation!
