A "double het sunglow" is a Hypo het Albino.

Therefore you've got a 25% chance of albino offspring.
You have a 75% chance of Hypo offspring (some of which will be homozygous "super hypo" - but without breeding trials this cannot be proven).

So you have a small chance of albino not hypo, a slightly larger chance of normal not hypo, possible het albino, the same chance of Sunglow (poss super hypo), and the majority will be Hypo (poss. super hypos) possible het albino.

Quantitatively thats

hypo to hypo =

25% normal
50% hypo
25% super hypo

het albino to het albino

25% albino
50% het albino
25% normal

or in other words

25% albino
75% normal (66% poss het albino)

If you combine the above percentages for the dh x dh


then you get

6.25% albino
12.5% sunglow
6.25% super sunglow
18.75% normal (66% poss het albino)
37.5% hypo (66% poss dh sunglow)
18.75% super hypo (66% poss het albino)


Cheers
