Default Interbreeding dwarf russians

A question:



interbreeding Campbells and Winter White, is the same genetic situation when interbreeding horses and donkeys?



I remember that if you breed a male donkey and a female horse you will have a mule, most sterile (not all, but there are very few excepions),



while if you breed a female donkey with a male horse, you will obtain a hinny, always (???) sterile...



thank you for your reply

It isn't quite the same situation, as I understand it.



Horses and donkeys are separate species, and they have a different number of chromosomes. This leads to their offspring having an odd number of chromosomes, and being infertile (the very occasional exceptions to this would likely be when there has been some error in the formation of zygotes in the parents, leading to the offspring having an even number of chromosomes).



WWs and Campbells are probably subspecies (Phodopus sungorus sungorus and Phodopus sungorus campbelli). Whilst they are genetically different, then can produce fertile offspring - hybrids. I don't know about the specific genetics of these species, I am not sure much is known although I have read articles where knowledge is alluded to.



For more on the debate about hybrid WW/Campbells there are a few articles in the BHA journal that are on their website http://www.britishhamsterassociation.or ... ations.php (look in the autumn 2000, winter and spring 2001 journals)

Default thank you Emma...

I read the 3 articles...as far I can I understand the question is still open about interbreeding, and some things need to be clarified...



...from my point of view, I completely agree with the theory that interbreeding is NOT recommended...



on the other hand, in Italy seems to be a lost battle, trying to educate people about this, because most of us Italians don't know anything about dwarf russian, most of us still don't know the differences between the two species or subspecies whatever...I am currently posting hundred of messages, reply, etc, on most of the Italian forums, but even moderators and administrators are not aware about this subject, the knowledge level, unfortunately, is very poor...



...we will see...



bye bye

Default PLEASE DO NOT BREED WW AND CAMPBELL'S RUSSIAN DWARVES

Hi Alberto, sadly the situation is not much better in the rest of the world either

I am against hybridisation of these two subspecies and encourage everyone I meet to maintain pure lines. We can only do what we can - keep up the good work

Default Hybrids

There are NO red-eyed Winter White Russian Dwarf Hamsters therefore unless it is an Albino Campbell's it is a hybrid of the two species. I would urge you if you have one of these not to breed with it, but to keep it as a pet only. Be careful housing it with pure bred species also as fights may break out as they mature. Albino Campbell's Russian Dwarves are quite fluffy compared to the other colours. (Those with the Platinum pattern are the same.) I cannot see the hamster in your top two photographs very clearly to say whether it is a Campbell's Russian Dwarf or a hybrid - sorry.
