Thanks Julie, three of the litter have reasonable unders so I'm getting better!julieszoo said:Looking good Lian!
And next year I hope to have black ones thanks to CaitMouseBreeder said:Yes rumpwhite is the proper name for the variety. You can create it in any colour you like, and show it any standardised colour. It is a dominant homozygous lethal gene.
If a mouse has rwo copies of the rw gene it dies in utero at a few days after conception. This is not harmful to the mother in any way, it just means smaller litters. It is fine to breed rumpwhites together, and in my experience produces the best markings.scatterbrain said:They really are lovely----in what way is the gene lethal? Is it a variety where only one parent can be rump-white and if so which varieties it most commonly crossed with? My instinct from breeding other species would suggest self varieties but as I know nothing about mouse genes I could be completely wrong![]()
Mousebreeder can correct me if I am wrong as I am new to rumpwhite breeding. a baby with 2 doses of rumpwhite will not be born. The litters are smaller than alot of mice have. I have not yet bred any rumpwhite to self, but from what I understand you will get self and some that look self but have a little bit of white such as white on tail. I breed rumpwhite to rumpwhite.scatterbrain said:They really are lovely----in what way is the gene lethal?
