They kind of look like my light olive axie minus the xanthophores.
I'm probably horribly wrong, but if 'light olive' was in fact a recessive gene different from wild-type (I'm not 100% sure from my research if it is?) then an axie expressing 'light olive" + the melanoid gene could look like this... maybe?
I am very interested in axie genetics and would love to know the genetics of your amazing colour variants, but understand completely if you wish to keep them a secret :wink:
