REW vs BEW

[Bad Habit]

I don't have any breedings like this planned, nor do I have the genetics for it in my permanent bunch, but I was tending to the rescue babies today and it got me thinking.

Let's say you had a pair and they came from a BEW x REW breeding. So they both have half the genetics for BEW and half for REW.

You breed them together, and a baby gets the genetic information for both BEW and REW from each parent.

What would you get?? Which would win out, BEW or REW? Or would you get a weird purple eyed rabbit?

Pretty sure REW would hide the BEW, since it can hide everything else.

The BEW masks colors just like the REW does, so you would have some full color kits, just vienna marked, or not vienna marked but carriers. The vienna marked resulting kits would now carry REW, but some would still carry full color as well, so you should get some full color kits, some REW kits, and some BEW kits with ruby cast to their eyes.

Let me see if I can work out a square for that one.

Interesting! I bet one is dominant over the other....according to some genetics guides REW is dominant http://www.firedoverabbitry.com/FDbreedBEW.html

None of these genes are independent of the actual genotype of the rabbit. There are still colors masked by both of these genes.

REW is dominant, but BEW still have a full color gene, and it is only partially dominant over the full color, only if there are two copies, so you are still giving the kits a copy of the full color gene with a copy of the BEW.


_____C___vv_ , but there is a full color gene there somewhere.

_____cc_____ full color masked

Cc, Cc, __c, __c, you have no idea what the second letter is for the vienna BEW. Could be _c, could be CC. So you could get Cc, Cc, Cc, Cc.

Then the REW does not carry Vienna, so the kits will be Vv, so some will have the vienna gene and some won't.

The REW also has a color, and paired with the color gene you can get whatever the color of the REW is.


Now the new kits all have REW __c___, but they could also have full color genes, so you could get full color ___C___ or REW ___c___ . or They are all vienna cariers, but some would have the normal V gene so not express BEW. Breeding to a BEW is sometimes just like breeding to a non REW carrier.

Then as more confusion, the REW gene will stripe the color from the Blue eye and give it a ruby cast.

Sooo... what I'm getting from this is, you'd get rabbits with weird purply eyes.

I was talking breeding a cc VV x CC vv, thus getting all kits that are Cc Vv. Then breeding two of those Cc Vv kits together, and only wondering about the eye colour of those kits who were cc vv. I understand that both REW and BEW mask the underlying colour, but one has to be dominant over the other, doesn't it?

 

[dragonladyleanne]

LOL, it suddenly occurred to me if somehow you DID get the purple eyes, and it bred true enough to be considered another variant, those babies would be called PEWs!!!

:rotfl:

no. A cc vv would be rew. A Cc vv would be bew. A Cc Vv would be normal colored with possible blue eyes or white vienna markings.

 

[Bad Habit]

But I'm reading that crossing rew with bew gives a bew a ruby cast to their eyes. That link up there somewhere said it, and a couple other pages I've meandered onto have said it as well.

Can't be PEW, as PEW is used for Pink eyed white in ferrets, guineas and rats, I believe. Would have to be VEW for violet eyed white.

Although there's apparently a brown eyed white... I suppose we could call that CEW(chestnut) or HEW(hazel).

Now we need some EEW(emerald) or GEW(green).

For what it's worth, my white baby has opened her eyes(I want her to be a her so I can keep her, LOL). I can't tell the colour yet though, but assume BEW... unless I got a CEW or HEW. Maybe even a VEW because Hannah has a ruby cast to her eyes.

And with that, I've just made my head hurt, lol!!

That's what I am trying to say.

But giving a ruby cast is not the same as purple eyes. There are other colored rabbits that can have a ruby cast to their eyes, like amber in Rex.

 

[akane]

A ruby cast would not turn the eyes purple. They would just look reddish in certain light and under camera flash more so than other colored eyes. It's the same as say a sable. They have brown eyes but if you look at them in certain light they have a reddish over color clouding the brown. It more covers it than mixes with it.

 

[Bad Habit]

sigh. there goes my dream of making millions with purple eyed rabbits!!

 

[Honorine]

REW is the one color thats really really not good to cross with BEW, because it does mask the blue eyes. Also REW is often less hearty than a colored rabbit, and BEW can have immune issues, at least in Mini Rex, so it would be a double whammy genetically. As for a 'purply' eye its been said that having chocolates behind your BEW can make the eye lose its blueness and look more lilacy, because chocolate based rabbits do have a ruby cast to their eyes. So you'd want chocolate behind your rabbits, not REW.

 

[BlueLove16]

you mean violet eyed rabbits right...lol

 

[Bad Habit]

Yes, that's right... violet eyed.

I'm actually buying a BEW doe that has chocolate in her lineage, and she has stunning eyes. Nice and clear blue.

 

[a7736100]

Not from REW X BEW but I got a black with Vienna marking, one brown eye, one eye half grey and half brown. Mother was black and don't remember if father had blue eyes or not. Both were free off craigslist. I need to start keeping more detailed records other than birthdays.

 

[Petlover500]

Thats so cool! You should post some pics!

I know.... same... I mean I keep their pedigrees, but I think It would also be nice to have other things. Like how many times they have been bred, what feed they are on, etc.
