Hey All

I've been getting my head round the use of the Punnett Square and have typically got the dom/co-dom and single recessive breeding understood.

My question comes now to Dbl Recessive breeding , in particular the codes used to denominate double hets.

I'll use the example of breeding for a Snow (Albino x Axanthic)

Albino = aa
Axanthic = xx

Breeding these together (aa x xx) would give me 4 x ax.

Now these should all be normal looking babies but all are carrying the recessive gene for Albino and Axanthic, a double het.

Would I be correct in portraying a dbl het albino/axanthic as AaXx for use in a punnet square?

If so, then would I receive the following theoretical results from breeding a pair of dbl het Albino/Axanthic?

AAXX Normal x 1
AAXx Normal Het Axanthic x 2
AaXX Normal Het Albino x 2
AaXx Dbl Het Axanthic/Albino x 4
AAxx Axanthic x 1
Aaxx Axanthic Het Albino x 2
aaXX Albino x 1
aaXx Albino Het Axanthic x 2
aaxx Snow x 1

Thanks!!
