Agouti and Non Agouti side colors

[TJ's Rodent Ranch]

So I'm currently working on compiling a list of Agouti and Non Agouti side color twins. I'm pretty new to genetics in general, so I've actually only got two sets of twins :')) 
I'll be looking into more of them, but I wanted to just go ahead and make it, even if I only have two.
I'm going to put them below in a list, and if you think of any as well, feel free to put them below and I'll add them to the list. Also, since I'm so new to this, if you see faults in my list, please feel free to point them out!




Agouti                  -            Non Agouti
_____________________________


Agouti                  -             Black
Dark Eyed honey -             Nutmeg
CP agouti             -             Burmese
LCP agouti           -             Siamese
Grey agouti          -            Slate
Polar fox              -             Silver nutmeg
Argente Golden   -             Lilac
Argente Fawn      -             Sapphire
Argente Cream    -             Dove

I believe nutmeg is actually the non-agouti form of dark-eyed honey.

Some others:
CP agouti - Burmese
LCP agouti - Siamese
Grey agouti - Slate
Polar fox - Silver nutmeg
Argente Golden - Lilac
Argente Fawn - Sapphire
Argente Cream - Dove

Yes, Dark-Eyed Honey is a Nutmeg twin, not a Honey Cream twin.

A Honey Cream might actually might have its own color name but it is genetically always a Dark-Eyed Honey (DEH). DEH is the base color.

However, because a Honey Cream is a spotted DEH, it is the A*/aa twin of a spotted Nutmeg of course - and you can write the genes down for it using the Sp+ label if you wanted - just stick it right at the end after Uw*. As long as you always remember that it is still just a Dark-Eyed Honey, and it's twin is still just a Nutmeg.

Because gene calculations don't usually make note of whether each individual pup in a pairing will be spotted or not - they just state the base colors you can get from the genes available. Noone (apart from a computer predictor) will list the spotted versions of expected pups from a pairing alongside the base colors (unless you specifically ask) as they are identical of course.


Next level info for why we don't usually quote the spotted versions:
It is well much easier to assume the spotting genes acts seperately - it doesn't of course - it is just easier when starting out or doing quick calculations.

When assuming this 'easier way' for your working out, the odds of the colors possible from your genes are still identical to your practice ones above (100%/50%/25% etc), just that there is the chance of spotting laid over the top of ALL the pups.

50% of pups from Aa x aa will still be Black pups - and spotting has a 50% chance across a litter - but that won't mean that all the Black pups will be spotted or not. If you want percentages of each of those colours being spotted you can actually work it out of course - it is just simple math - but when working with 2 or 3 different genes you start getting miniscule percentages for the multi-recessive ones. Once your percentages drop below 25% it get harder to 'see' those colours in a litter anyway (mainly because gerbils can have very small litters) so in a way working out the spotting varients complicates the guesswork and doubles your workload. If you are predicted 10 different base colours from a pairing - you will need to double your maths to get them all again in a spotted versions.

Technically as well - if you are adding all the spotted verisons into the pot - you are reducing the percentages of getting the original base colors as well - so instead of getting 50% Black and 50% Agouti - you will need to add the spotted ones in so your plain Black and plain Agoutis MUST fall below 50% otherwise they can't fit in to your original 100%. The extra math makes my head hurt - and basically - if you have an Agouti pup with a spot on their head - they are still an Agouti, right?

How's your color hunting going TJ's Rodent Ranch?

I have seen that new member NucleoWolf is also into genetics - so perhaps there is a tag-team in the making right there! Perfect timing...

Sorry I've been a bit spotty around the forum for a little while, and I've almost completely ignored this section, so sorry about that.
I'll update the list, and put together these genes so that I'm learning from it, and not just making the list longer, haha.

There will just be that one moment - and it will all come together.


No hurry to get back on here - just nice to be able to share some proper details.
