BS split Cameo X Cameo split BS offspring

[beluga3858]

I think I got this correct but am starting to wonder (see end)

BS split Cameo male X Cameo split BS peahen produces:

Males: Must be BS or split BS (one BS gene from male). Must be Cameo or split Cameo (Cameo gene from her)
- 25% BS split Cameo (looks BS) BS from her 50%
- 25% Cameo split BS (looks Cameo) Cameo from him 50%
- 25% BS Cameo BS from her 50%, cameo from him 50%
- 25% IB split Cameo split BS (looks IB)

Females: Must be BS or split BS (one BS gene from male)
- 25% Cameo split BS (looks Cameo) Cameo from him 50%
- 25% BS Cameo BS from her 50%, Cameo from him 50%
- 25% BS BS from her 50%
- 25% IB split BS (looks IB)

So, either this is wrong and I'd appreciate understanding why, or the odds are totally against us because our breeding of that pair over two seasons has produced plenty of BS males (drowning in them), a couple of BS females (pretty), a possible BS Cameo female (see my earlier thread), several Cameo females, but ZERO, none, 0, not one Cameo or BS Cameo males!

OK, so your pen consists of;

She came from a breeding pen with the following stock:

Male:
Black Shoulder split Cameo

Females:
Cameo split Black Shoulder
Purple Pied
White eyed Pied
IB Pied

Your IBBS/Cameo cock and the Cameo/BS hen should produce 50% IB of both sexes and half of those BS. The other 50% should be Cameo of both sexes and half BS. If this is not happening then the hen is not really Cameo. When he is bred to the other three hens half of the hen chicks will be Cameo and the rest IB and IBBS if any of them are split to BS. Can you share a pic of your Cameo/BS hen?

It would also be easier for us to follow if you state Color/Pattern/Split in that order.

Thanks for the reply - hopefully this attempt is a little more correct?

IBBS/Cameo male X Cameo/BS female produces:

Males:
Must be BS or split BS (one BS gene guaranteed from him)
Must be Cameo or split Cameo (one Cameo gene guaranteed from her)

Genetic	Appearance	Notes	Odds	Actual
IBBS/Cameo	IBBS	2nd BS from her 50%	25%	Lots ~80%
Cameo/BS	Cameo	2nd Cameo from him 50%	25%	None
Cameo BS	Cameo BS	2nd BS from her 50%, 2nd Cameo from him 50%	25%	None
IB/Cameo BS	IB		25%	(not tracked)

Females:
Must be BS or split BS (one BS gene guaranteed from him)

Genetic	Appearance	Notes	Odds	Actual
Cameo/BS	Cameo	One Cameo from him 50%	25%	Several ~15% **
Cameo BS	Cameo BS	2nd BS from her 50%, One Cameo from him 50%	25%	Rare ~5%
IBBS	IBBS	2nd BS from her 50%	25%	Rare ~2%
IB/BS	IB		25%	(not tracked)

** Some of these could come from other pairings in the same breeding pen

Really I'm just venting because I'm disappointed that we've so far failed to get any Cameo color males

Heading out there now !

The law of averages is a fickle thing but half of all the hen chicks in that pen should be Cameo hens. It is very odd that you haven't produced any Cameo cocks with the Cameo hen.
