Afternoon all;
I've been trying to figure out what the genotype of my axolotls is based on the colours of the efts that they just laid. I have been following the guide on Axolotls.org (Here) and I think I've come to a conclusion.
using this:
So the adults themselves aren't albino so that means that they need to be A/a or A/A, and they are both dark which means that they equally must be D/d or D/D. The efts of the two are about 50:50 dark and light so they are definitely heterozygous for darkness and possibly albinism (but I won't know albinism until later on).
So A/a (m) and A/a (f) will either have 25% chance of having albino offspring; The same as D/d and D/d with the same 25% not dark.
If both parents were A/A and A/a or D/D and D/a then none of the offspring would be albino or pale so both parents MUST be heterozygous for both of those colour variants.
As far as I am aware both the adults are melanistic and don't have the melanoid pigment associated shiny eyes. Both eyes in both individuals are all dark meaning they are both m/m for melanism.
All together that means the adults are either
m/m ; A/a = Melanistic Albino
or
m/m ; D/d = Melanistic Dark (wild type?)
what I don't really understand is the whole axanthism thing comes in?
Here are some photos which may hopefully help to support what I've just said above...
