So for the problem of over melanized .....an over melanized hen with a good colored rooster will give me good colored pullets and cockerels just as an example of pairing but an over melanized rooster with a properly colored hen will only produce good colored cockerels and my hens will remain overmelanized. this was a big problem a couple of years ago, hens had no hackle.
The one thing I have noticed on this thread is that the BCM in general keep getting better and better. A lot of really nice BCM.
Don t go too fast my friend .
it is quite complicated than that .
we are only talking about the Silver and gold sex linked gene ( S/S .S/- and s+/s+ .s/-) those genes are responsible or just a hackle ,saddle and the lancet colors of the Rooster and hackle of the hen .
the Rooster have both copies S/S ( Birchen ) or s+/s+ for the BCM,that why his hackle ,saddle and lancet are colored .
the hen on the other hand has only one copy S/- ( Birchen ) or s+/- for BC . so only her hackle is colored .
here who does work =
1) Rooster with a well colored hackle ,saddle and lancets MATED TO hen with colored hackle = progeny will be =
Cockerels = they will get 50% of they color from they Sire ( Rooster) ,plus they ll get the other 50% from they Dam ( mama hen ) .well colored cockerel.
Pullet get they 50% from they Sire ,that will cover they hackle area that all . they get nothing for mama or they can t express it = pullets with a colored hackle.
this method is true in the absence of any modifier genes or inhibitor genes.
2) Rooster with a well colored hackle saddle and lancets MATED TO Hen without a colored hackle ( this hens still is S/- for a Birchen and s+/- for a BC ,she has Silver or Gold but with a presence of other modifying genes like sort of Melanin etc..........) the reason she is black = Progeny will be =
Cockerels = half way colored ,maybe the hackle and a little part of the lancet or just hackle that all . those colors are from they Sire ,nothing form mama as far as colors because she is black but they will inherit the modifying genes from her.
Pullets = most of them will have a colored hackle .
3) Rooster without a colored hackle or Lancet /saddle ( half way colored ) MATED TO Hen with a colored hackle = progeny will be =
Cockerels = half of them will have a colored hackle ,saddle and lancet .the other half will be half way colored .
Pullets = most of them will be black .only few with a spotted hackle or just around the head and the upper part of the neck .
4) Rooster fully black ( presence of modifying/ Inhibitor gene s ) MATTED TO Hen with a colored hackle . progeny will be =
Cockerels = half black and half half way colored
Pullets = all black
those Black progeny ( Pullets or Cockerels ) are still gold or Silver carriers but the modifying genes are interfering with the expression of it .
THEY ARE NOT PURE BLACK .
next time we talk about the Autossomal Red Ar responsible for the color of the ears tufts . shoulders and upper chest for the Rooster . the ears tufts and spotted chest for the Hen .
for the chooks to be well colored both of those genes Sex linked and Autossomal red have to present .
chooks man
