Barred x Patridge

[featheredplanets]

Male barred over female partridge makes all black chicks with red leakage.

Female barred over male partridge makes barred males and black females, with red leakage.

Is this right please?

Male barred over female partridge makes all black chicks with red leakage.

All the chicks get white barring, too (in addition to the black with red leakage.)

Female barred over male partridge makes barred males and black females, with red leakage.

Correct.

Is this right please?

About 3/4 right

Correct.


About 3/4 right

Thank you!

Oh, I forgot to add: there is a chance of silver (white) leakage on some of the chicks, instead of red or in addition to red. This is because some black chickens are genetically Silver.

All Barred Rocks and most self barred breeds are Silver at the sex linked S locus due to Slow Growth Feathering is closely linked to Sex linked Silver.

Also Extended Black/Partridge E/eb will produce Nearly All Black phenotype I would say that most if not All should be Solid Black.

First because eb is a revertant mutation of Extended Black( e+ - ER - E- eb) and because Partridge also carry the Pg pattern gene which is also an Eumelanizer So a E/eb, Pg/pg+ will almost always lack any gold/silver leakage.
