No-- I was talking about breeding white on white- so -- can I "assume" these rabbits came from "colored" / "white", great grand parents-- with white young sold to me as "pure bred" ?

If you cross a white to a white you should only get white. Unless you are crossing bew to rew or pew. You need 2 of each of those genes to make more solid white. If one is a rew and one is a bew you will just get colored kits that carry vienna/bew and carry rew. If your white throws color with other whites it may be a charlie broken or a frosty/ermine. Check the eye color because if the rabbits are the same gene combination to make white you should always get more identical offspring.

I am confused. It is impossible to get any other colour than white if you breed two white rabbits.

UNLESS

One is a blue eyed white (BEW / double Vienna) Do you have a BEW buck or doe?

There are couple colours the "look" white but are actually very light chinchilla or sable or they are an extremely high white broken or a broken vienna or dutch and rather than having pink or blue eyes they are brown or grey.

True white rabbits only have pink or blue eyes.

A quick look shows both does that throw some color have a pale grey/ blue eye [not pink like the ones that have never had any color.] --- the colored offspring are gray/white with a patern like "Dutch" -- or all black, with a little white on the front foot.

Yep you have 2 different versions of white. Red eyed ones are carrying 1 set of white genes and blue eyed ones are carrying a different set. They do not combine. The dutch pattern may contribute or it may just be a separate gene hidden by blue eyed white genes.

thanks-- it is a bit confusing , and has never happened in all my years of rabbits-- before this-- "white" on "white" always made "all white"-- Oh-WELL -- they are "pretty" and I just can't help but keep a few to see what they "do"- the "mom" had and weened 10 the last 3 litters, so they can't be all bad-- but the Black does are a little smaller and more compact then the others in the litter.

It sounds like the does are BEW but genetically are chinchilla which can muddy the blue eyes and make them more greyish, if you get REW in the litters as well then they carry this gene too.

The Vienna gene is fairly new and not very common in large rabbits so I'm not surpsed they are smaller than you're New Zealand's as they probably have smaller breeds in their ancestry.

Individual rabbits can only have one father as the egg will only accept one sperm, less then 1% of the time two sperm can penetrate an egg but the embryo dies within a few hours.

A litter can have several fathers, so kits born at the same time will be half siblings on their moms side.

There is also the white-ear mutation, discovered in germany. They are becoming very popular and more common here in the Netherlands. The gene is mostly bred in loffelohr (spoon ear) dwarfs, holland lop and french lops too. What would this gene be called in the US and the loci it is found on? Or will it not since they are non existent in the US?

I believe it inherites co-dominant (incomplete dominant?) Out of a WE and a normal parent you get 50% with the gene. The gene is not carried, it shows when its present. But i dont know how it expresses when the gene is double (homozygous).

This buck has 2 white genes.. Vienna and the White ear combined.

We dont have white ear or spoon ear over here so I am not familiar with the genetics :)

Only recently has the pink eye / lutino gene shown up in rabbits and understand it mostly from my experiences in breeding mice.

Nope :)

A self chinchilla can have startling blue eyes as kits but mine always get darker as adults.

Do you have any information on the colour of parents, siblings or offspring?

Is there any white spots on the rabbit anywhere?
