I understand rule number one very well. I have know it for years. But today is the first time I have heard of the exception.
There is one exception to rule number one; a red sex link that is a non-barred and non-dominant white male can be used in a black sex linked cross.
Since there is one exception to rule number one;
a red sex link that is a non-barred and non-dominant white male can be used in a black sex linked cross.
I'm not understanding why you can't make a black sexlink with red sexlink hens ..
There is one exception to rule number one; a red sex link that is a non-barred and non-dominant white male can be used in a black sex linked cross.
This is why I ask ..
I want to make sure I have this right..
If I cross a red leghorn roo over a silver leghorn hen I get a red sexlink ,, now ,,if I cross the offspring red sexlink hens with a rir roo I can get black sexlinks ???
