[Nancy's Hamsters]

Using just the pair you state above, unless your female is or carries Cream or Cinnamon all you could get in offspring(again using the pair you stated above) would be Golden and Yellow males(pending on if her Single yellow gene was passed on or not), and Golden or Golden Tort Females(again based on if she passed on her single Yellow gene or not). If the Banded male is Homogeneous for the band gene all pups would be banded, if not then some will be banded and some solid(Genetically based 50% would be banded, and 50% solid, but seldom does the results end up that).

I see from your public profile your have shown hamsters occasionally, so are in a country which has Hamster shows.

That said:Your Cream carrying Yellows will not do well at all in a show and all the resulting yellow pups from the above pairing would only be good for Companion/pet hamsters. Cream masks(covers up) Yellow and even when just carried will cause the Yellow coloring on a tort to completely lack any ticking , and on a Yellow male it will wash out all ticking making the hamster poor show quality.

If the above female hamster should carry cream, then you can have what to the naked eye looks like Black Eyed Cream, but actually will be a Yellow, or a Tort genetically. Cream Masked Yellows, and Torts are so much like BEC in looks many have shown as BEC only to be disappointed when bred by producing Yellow or Tort pups. A fact which is very frustrating if you planned a litter to continue on a show line of BEC.

You could do much much better with Breeding Yellow with a different pair of hamsters then your example. It takes just as much time, care, and effort to breed quality hamsters who have show potential, then it is to breed just companion/Pet hamsters.

That said it would completely depend on what your goal is for breeding Hamsters. If you actually have a pair as described in the example then you would be producing nice Goldens who will carry Cream and Cinnamon, But your Golden Torts would be poor quality show stock and also would not be sought for future Show stock producers as the Cream is carried washing out the correct desired Ticking on the Yellow patches.

Hope this helped you understand more about the Yellow gene.
