Robo punnett squares

[kiania]

Don't suppose anyone knows of any robo punnett squares, do they? I've read a few assorted websites on the various colours, but genetics is not my strong point, so working out dom/rec genes, and which genes cause which traits (as well as what the short-hand is for each trait - can't even find that out right now!) is causing me problems. Punnett squares are easier to read, so ever hopeful someone has made one, or knows of one as my google-abilities are failing me

I think you're confused about what you're asking for as one can make a Punnett Square for anything! You can make your own Punnett Squares. If you're uncomfortable with doing it yourself, there are blank squares on line in which you input the parents genotypes and it will give you all the possible genotypes of the resulting offspring.

I think what you're really asking for is a place that lists all the Roborovski mutations and corresponding genotypes. I don't work with the robos and don't really know where to send you other than Oak Farms Rabbits and Rodents- Roborovski Colors

She's done a great deal of work identifying the Roboroski mutations and has a forum on her website discussing the Roborovskis. I'm sure you can ask there what genotypes they are using, they are most likely even listed there already.

If you're still finding yourself lost with just learning the basics of genotyping, then please work through the River Road Hamstery's Genetics Tutorial. While it's using Syrains in the examples, the ideas, Punnett Squares, gene transference, etc... is the same no matter the species, Syrians, Roborovskis, Dogs, Cats, Alligators, etc...

I'm asking for a punnett square because I don't have the information that goes into one - I'd settle for that and make my own, but I'd still need to know which genes are involved.

I've read Tammy's stuff (it is rather the cornerstone on what everything else seems to be based on), but it only seems to mention the mutation names, rather than what their shorthand is, or which is more dominant. It says things like "dominant white faced gene", but doesn't say dominant to what - to agouti? To husky? To agouti but not husky, or husky but not agouti, or both? And what about pied, how does that fit in?

Erm, as far as I know there isn't a shorthand for Robo genes I've never found reference to one. Most websites I've found don't even mention the whole range -- and so many contradictory claims about white faced being dominant or recessive -- and Tammy's is the best website out there. She has said before (somewhere in passing on another thread) that it needs updating, though.

Dominant white face is dominant to agouti and combines with husky to produce platinum or white, depending on the number of husky alleles I reckon pied must be dominant, as there are so many of them cropping up in pet shops, but I honestly don't know.

Hiya,

Sorry I haven't got much time for a detailed post at the moment, buti just wanted to say that basically a Dominant gene means that for a hamster to'be' that colour or pattern it only needs to inherit one copy of the gene i.e. One copy from one of it's parents.

A Recessive gene means that for a hamster to 'be' that colour or pattern it needs to inherit two copies - one from each parent.

There are two Pied genes, one dominant and one recessive.

Thanks for the comments on my site guys, I really appreciate it . But it really does need updating! It's on my list!

Is that a typo, or are there really two pied genes as well as two white face ones? If so, that's going to get extra confusing...

Your site is the best out there, honestly I've looked all over the 'net for Robo genetics I'm a little bit obsessive on occasion

[Tammy22]

No, it isn't a typo.

There are two different Husky genes, as you know, one Dominant and one Recessive, which combined create the White Robos which are born with black lining on their ears and black undercoat.

There are also two different pied genes, one Dominant and one Recessive, which combined create the 'Head Spot' robos and also the Pure White robos with no undercoat and no other colour anywhere - pure white!

Yes, it can be very confusing! Lol

... Well, that explains how head spot Robos are created, I was wondering about that

Can the two versions of pied be told apart by looking at the hams, like white face and husky can be (sort of)?

Also I find it very bizarre that there are two different sets of genes in Robos that do similar things but one of each set being dominant and one recessive It seems like such a rare thing to occur, statistically.

[radiocricket]

Right now the robos are the "in" hamster. About two years ago, one US distributor contacted a bunch of hobby breeders looking to buy 2,000 robos a week! That's right, 2,000. Obviously, all the hobby breeders combined couldn't do that! It's only the commercial breeders that are able to produce those quantities.

So think about it statisically, if the commercial breeders are producing that many robos (and that distributor would only be one of their clients), just how many are being bred?! If you expect one mutation out of every 100,000, well then, it's not surprising that we're seeing so many mutations suddenly.

To further prove its originating from the commercial breeders, these new mutations can be found in the US pet stores. They're arriving here through the commercial circuit so that means it's in the commercial breeder's lines.

Oh, I know there's lots of mutations coming up all the time It's more that [characteristic] can be caused by two different genes, [dominant gene] and [recessive gene], which combine to give [variation one] and [variation white], for both white faced/husky and pied. The odds of [dominant gene] and [recessive gene] both causing basically the same phenotype, and combining in two ways to make two others, is rare enough, never mind that it's now happened twice!
