Please tell me the father(s) of this pair (Calling genetics experts)

[ChickenCharmer]

Here is a cockerel and a pullet that both come from a golden sebright hen. I only need help finding out who the father is.
The possiblities of a father are-
Black tail buff Dutch
Red Pyle OEGB
Fawn Silver Duckwing OEGB
Porcelain Dutch

Cockerel
He has a single comb. His breast plumage is sort of golden laced, and the rest is a shiny lustrous greenish purplish black, just like s Black Sumatra, with a golden streak through the middle. Also he has a very very long tail.
body

wing plumage

front

Pullet
She has a rose comb, like her mother. Her plumage is a variety I've never seen, but it vaguely resembles triple laced.

Again, the fathers could be
Black Tail Buff Dutch
Red Pyle OEGB
Fawn Silver Duckwing OEGB
Porcelain Dutch.


Thanks for the help!

I'm guessing the black tailed buff, but the fawn is also a possibility.

ETA: I'm NOT a genetics expert, but sometimes I play like one on BYC!

the BUFF...

 

[ChickenCharmer]

The buff? Are you sure on both of them? Because the plumage patterns look very different to me...

But how could a BTB create such interesting designs (on the pullet) with a GL sebright? And the cockerel looks like mostly sebright (except for the comb). It's strange to me. With my other mutts it's easy to tell (most of them are fathered by the Pyle) ; they have their mother's bodies with pyle plumage. Others are just Black tail Buff-- easy to tell the father, but this cockerel looks like only his mother and the pullet doesn't look like any of the roosters.

Genetics are very confusing to me... (I'm only fourteen and don't have a clue about them.

) Try to explain it simply to me

so... any more guesses to the pullet and/or cockerel?

Thanks for the help

The pullet could be from the red pyle if he is het for dom.white

The cockerel should not have a single comb if his mother is a pure sebright.

He still could pass as single laced so his father probably contributed one Columbian: blacktail dutch or porcelain dutch
Since the lacing is obvious the father "must" have something extra like Pg or Ml.
The pullet could be from one of them also.

I got a similar pullet without any Columbian in her:

Her brother, note that he is not laced.

 

[ChickenCharmer]

So the pullet's father is the Pyle, Blacktail, or Porcelain, and the cockerel's is the Blacktail or porcelain?

And Henk, how would I know if the mother is not pure sebright?


Anyone got more guesses?

 

[Henk69]

A pure sebright wouldn't throw single combs.

They also use single combed birds to help with fertility. Birds with a double dose of rosecomb can have fertility problems. The hen-feathering doesn't seem to help with fertility either I think.
