Very nice presentation and thorough!

Without any formal genetics training since high school I do have a few questions.

I've gathered that there have been several competing genetics notations coming from different fields. Is that still the case or is this an agreed upon standard? I see where you used the color coding to distinguish the normal for albino allele “N” from the normal for clown allele “N”. Do you have anything against using the notation where the same letter is used for both variants at a locus of an interesting mutation like “C” for normal for clown and “c” for the clown variant and similarly “A” for normal for albino and “a” for albino? I know this isn’t perfect either and will get more complex as we identify situations with more than 2 possible variants at a locus (like the Platy complex). I’m also unclear how to handle the capitalization in cases of co-dominance. I’m just thinking the common “N” is confusing and color coding might not always be available to keep it straight.

Also, are you aware of any homozygous spiders?
