    Also, if you did want to learn more about different combinations of genes so that you may someday get into (more serious) breeding world of ball pythons and morph market are amazing resources. I know a lot of people were linking WOB's genetic calculator but you can also search that site to see what each gene looks like on its own and in different combinations. Warning: there is A LOT of information there lol

    Morph market is good because it sometimes has animals that aren't on WOBs and it gives you an idea of pricing (if you're in the US) so you'll know which animals will fit into your budget while still allowing you to produce some of the animals you want the most.

    ***Appolgies in advance if this is what was explained in that previous post***

    Strictly speaking as others have explained and I'm sure you understand it all comes down to the alleles. If an animal inherits a co-Dom allele from both parents it will be the super (ex. White wedding) if an animal inherits a recessive allele from both parents it will be a visual recessive (ex. albino). So if you look at it this way you can see that both of your animals have two copies of the same allele and are thus homozygous for that trait. For any given trait the babies inherit one copy of each parent's alleles. Since the parents are both homozygous they will always pass on the same type of allele to the babies thus all of the babies will be Russo het albino.

    It gets more complicated when you aren't working with homozygous animals because then you start playing with the odds. If you followed the above you can see that if one of the parents is heterozygous (only carrying one allele for the trait) it will only pass that allele to 50% of the offspring (passing the other "normal" allele the rest of the time). Thus Russo X normal = 50% Russo & 50% normal. It gets more complicated when you add more genes or are working with recessive genetics (since recessive hets or heterozygotes are visually normal) so I won't talk about that.

    Feel free to post if you have any more questions. I love talking genetics haha
