If I breed my castor buck with my REW doe will any babies be REW?

My buck i think is a castor mini rex & my doe is a REW with ruby red eyes with a hidden gene i dont know what it is shes a mini rex to, she had one litter all look like dad but with white legs, this is her second liter be due end next week was curious if any be white with red eyes like her? Just wondering Thanks

There are a whole bunch of genes that influence the color of a rabbit's coat; with Ruby-eyed Whites, the only genes you know for sure just by looking are two copies of the REW gene. In order for a rabbit to be a REW, it must have two copies - one that came from the mother, and one that came from the father. The only way for your doe to have REW babies is for you to breed her to a buck that has at least one copy of the REW gene. Since your buck is not a REW, we know that he doesn't have two copies of that gene, but he might have one copy - do you have a pedigree for him, by any chance? If he doesn't have any copies of the REW gene, you could breed these two together forever and never get a REW baby. The white legs on the last litter sound like the doe may have a copy of the broken gene, but it doesn't sound like the combination of this buck and doe will produce babies with enough white on them to be "good" brokens.

I can't say for sure whether you might get any REW's in this next litter - sometimes, even though you know the genes are there, the color you are looking for just doesn't appear in the litter. But the more litters you have without at least one REW baby in it, the higher the likelihood that your buck doesn't have a REW gene. Does that make sense?

I am just curious @Bunnylady, what is your scholastic or professional background? Science related?
As I said, just curious

Yeah. Things like genetics are home territory for me. Computers? Not so much.

I have a secretary and tech guy for the computers. I think I can hold my own though.
Before I studied ministry, I earned an A.S. in Conservation Law Enforcement. Yah, I wanted to be a possum cop. I did a lot of biology, wildlife management, forestry, and oh yah the criminalistics and law enforcement studies, but no genetics or husbandry. I would have to go back a little further to growing up on the farm and high school ag days for animal husbandry or Biology for basic genetics.
Today, I live on church property in the country with my wife and boys, lead a small church of around 100, and raise my rabbits and have a hay field behind the parsonage and shed. Still just guessing at genetics

Thanks, everyone I guess i will wait and see. I contacted the breeder we got her from and she said her hidden gene is a broken gene. So thats why last babys had white legs with brown spots. I dont have pedigree for him i bought him at pet store in another state. From what i searched on the mini rex colors online he looks like a castor!! When i go out today to feed them i will take a pic of him to post. If i dont get any white or broken colors thats fine im looking into another broken buck or REW for her! Thanks again

Here's a pic of my buck is he a castor? If not what color is he? Thanks

Yep, looks castor to me.

@Bunnylady Thank you!! Im looking into getting a broken or tri color buck to breed with her to!! Thanks again everyone will post pics of her babies!!

One word of caution when it comes to breeding brokens. The gene that causes the broken pattern doesn't just affect the coat color, it is also involved in the development of the digestive system. Rabbits with the broken gene have "reduced gut motility" - in plain English, the process that pushes food through the digestive system just runs slower than it does in rabbits without the gene. In rabbits that have one copy, it's just a little bit slower, but things go a lot slower in animals with two copies.

There is a condition called GI stasis where the digestive system just shuts down completely. This is an emergency situation when it happens; it will kill the rabbit if it doesn't get corrected and can even kill in a matter of hours. This could happen to any rabbit, but as you can imagine, a rabbit whose digestive system is already running slow is at greater risk of it. It is always important that a rabbit has access to lots of fiber (usually in the form of hay) and fresh water at all times, but for rabbits with two copies of the broken gene, it is of critical importance.

Some breeders think that the slow-running digestive system issue is important enough, they avoid creating such animals entirely by not doing broken-to-broken breeding.
