What is the difference between the two?
Which one is responsible for the red in a black breasted red/red duckwing male?

Are you already familiar with the gold gene? Because I know it's present in that variety, and absent in Silver Duckwing.

Mahogany is considered a modifier of gold--makes the shade darker or redder (found in Rhode Island Reds, for example.)

For autosomal red, I haven't really figured it out myself. I've seen a couple articles about it, so maybe they can help you:

Mahogany is what causes the red duck wing. I don't totally understand how autosomal red works but I think it is a gene sometimes present in gold birds which only shows up when it is crossed with silver, causing red shoulders which are difficult to remove.

Autosomal red isn’t sex-linked, so can appear on a hen or rooster pure for sex-linked silver. It can even cover much of their silver in some cases. I don’t know much about mahogany.
