Question
hi i have just bred my caster rex with my black rex what colur will i get

Answer
Dear Maria,

Unless you know the heritage of each of these rabbits, it is impossible to know the colors the babies will be.  If either parent is harboring the same recessive alleles for colors, then the babies could be colors other than black or castor.  But if you don't know what other coat color alleles are hiding in the parents, you'll have to wait and see.

If the castor bunny is homozygous for all gene loci coding for the castor color, then the babies will likely be 100% castor.  But if not, there could be a mix of colors.

For a nice overview, please see:

I hope this helps.

I've lived with companion rabbits for more than 35 years, and consider them members of my family. I can answer any questions about the biology and health of rabbits, from the commonplace to the unusual. But please note:

RULE #1:
THE INTERNET IS NOT THE PLACE TO SEEK HELP IN AN EMERGENCY.

...it is an EMERGENCY.

Find a rabbit vet at www.rabbit.org/vet for immediate help, and don't risk your bunny's life by spending time asking questions online! If you can't get in touch with your vet, read these Emergency Sick Bunny Instructions.

If you have found a wild baby rabbit, please read these EMERGENCY INSTRUCTIONS FOR WILD BABY RABBITS and then use this link to FIND A LOCAL WILDLIFE REHABILITATOR who can give you the right advice.


RULE #2:
Help me help you! Please make your subject line informative if you have an urgent question. then LET ME KNOW IN THE SUBJECT LINE so I can give your question highest priority over non-urgent questions. If you don't do this, then I can't guarantee timely assistance!
