What big ears lol

I hope so, only cause i dont want to breed her to a mini buck..... maybe the people i got her from have another half breed male from another mother. .... but she's not even 2 months and already is almost 3 lbs so that's promising to me. She's so nice and runs up to greet me and loves getting picked up etc.

What are you wanting to breed her with? Sorry for all the questions I just really love all things rabbit.

..... well i have pure bred american chinchilla 2 does and a buck...... BUT i love colors so I'd buy something her size with broken colors maybe a newzealand.... it all depends on her weight and body structure at 6 months

The father was a mini rex and the mom was a new Zealand. .. I saw the parents.... I just hope her size is somewhere in between....

As boring as it is to repeat myself - this is NOT possible. New Zealands DO NOT have the gene that creates the Rex coat. The doe is at most part New Zealand. The gene for Rex is recessive; a rabbit has to inherit the gene from BOTH parents to have the Rex coat. Whatever kind of coat the dam had, she had to have the gene for the Rex coat to have a baby with the Rex coat, which means somewhere along the line, she has a Rex (or very possibly, Mini Rex) ancestor. Since you can't be sure what all the dam is mixed with, you can't be sure how big her babies will finish up when crossed to a Mini Rex.

Okay I get what you're trying to say now I understand...... when I saw her mom she didn't have a Rex coat but the father did the mom is probably half Rex.... which is why mine has a Rex coat so you mean both parents carry the Rex coat Gene order for mine to have a Rex coat???.
.... I knew I came to the right place to ask questions..... the father was also not too mini either lol

The maximum showable size for a Mini Rex buck is 4 1/4 lbs. To be that small, he would need to have the dwarfing gene. Mini Rex, Holland Lops, Jersey Woolies, etc - all of the small breeds that were developed from the Netherland Dwarf require the dwarfing gene to meet the size requirements set out for the breed. Unfortunately, the dwarfing gene is what is called a lethal gene - any animal that inherits a copy of it from both parents will die, typically within 3 days after being born (people who work with the dwarf breeds call these double dwarfs "peanuts"). So even grand champions of these small breeds must have only one copy of the dwarfing gene, and one copy of the normal growth gene. Breed two animals like that together, and some of the babies will not get the dwarfing gene from either parent, but instead get the normal growth gene from both of them. Some people call these animals "false dwarfs;" they are maybe a pound larger than their true dwarf siblings, with slightly longer ears, faces, bodies, and limbs.

Some people will use false dwarf does in their breeding programs; they call them "brood does" (some folks I know call them "big ugly does"). These big gals aren't showable themselves, but they can still produce showable babies if bred to a true dwarf buck. You have to be careful, though - even a false dwarf breeding animal can't be but so big, or even its true dwarf offspring will wind up oversized.

You say the buck wasn't all that mini; sounds like he was what some Rex breeders refer to as a "midi Rex" (an animal that is too big to be a Mini Rex, but nowhere near big enough to be a standard Rex). That sort of thing happens a lot when people just breed for "pretty" without paying any attention to the breed standard, and it drives serious breeders nuts.

WOWWWW thank you as well for this explaination.... I Really like the rex breed and will keep looking for standard sized ones.... my little fawn one , we'll have to see how big she gets, she's adorable and runs up to me etc. I'll keep her for breeding. Hopefully she fills out around 7 to 8 lbs full grown , she's already almost 3 lbs at 7 weeks lol

What type of rabbits do you raise, it's great you know all the genetic stuff!!!!!
I do have a trio of American Chinchillas tattooed etc. Then I like having some mutts for color and variation....

She sure is cute!

Do you raise rabbits as well if so what kind????
