The pedigree for this pairing can be found at the bottom of the page     Dmtn Chester Dumbo Russian Blue carrying Hairless and Siamese. There is a possibility he is genetically Burmese and carries RED [du/du a/a d/d C(h)/c(h) Hr/hr] and possibly [Bu/bu and R/r] Chesters father is hairless making him a hairless carrier [Hr/hr] His mother is a Wheaten Burmese meaning that there is a 50% chance that Chester is genetically burmese. The only other possible recessive is RED from a great grandmother.   Dmtn Blueberries and Cream Dumbo Russian Blue Siamese carrying Hairless. [du/du a/a d/d c(h)/c(h) Hr/hr]   Blueberries father is hairless making her a hairless carrier [Hr/hr] Since Blueberries is a siamese we know that she is not genetically burmese like her mother, or it would show. The only other possible recessive is RED from a great grandmother   *The only markings I would expect to see are Irish and Selves* *In an attempt to keep this rather simple, I have chosen to leave out the markings genes in our calculations*   mendel chart for Dmtn Chester (listed down the left hand column) X Dmtn Blueberries and Cream (listed across the top row)      a  a  d  d  c(h)  c(h)  du  du  Hr  hr  a  a/a  a/a                  a  a/a  a/a                  d      d/d  d/d              d      d/d  d/d              C(h)          C(h)/c(h)  C(h)/c(h)          c(h)          c(h)/c(h)  c(h)/c(h)          du              du/du  du/du      du              du/du  du/du      Hr                  Hr/Hr  Hr/hr  hr                  Hr/hr  hr/hr                                                                                                                                            Litter calculation:                                                                                                                                                                         100% black based (no agouti)                                                                                                                                                                         100% russian blue (half will be rb siamese)                                                                                                                                                                         50%   siamese (possibility of burmese)                                                                                                                                                                         100% dumbos                                                                                                                                                                         25%   hairless    My final mendel calculations for a litter of 9: 4 or 5 - Russian Blues 4or 5 - Russian Blue Siamese (possible russian blue burmese if Chester is genetically burmese) all will be dumbos two of the above will be hairless   The actual outcome for the litter of 9 2 - Russian Blue 4 - Russian Blue Siamese 3 - Russian Blue Burmese all dumbos two of the above are hairless (Russian Blue & Russian Blue Burmese)   ~the babies~         Pedigree Of Dmtn Chester x Dmtn Blueberries and Cream D.o.B 03/25/2009 Breeder 13MR 13 Moons Rattery Parents Grandparents Great Grandparents Great Great Grandparents Dmtn Chester Dumbo Russian Blue STUD Roswell Hairless CWR Benton Himalayan Hairless CWR Nunez Himalayan Hairless RRLM Lady Utsu Black Berkshire Hairless RRLM Fran Fawn Dumbo Hairless RRLM Snoopy Russian Blue Agouti Dumbo RRLM Eva Black Self Dumbo RMIS Trinity Russian blue Wheaton Burmese dumbo RMIS Chocolat Burmese LVM Truex Russian Blue Point Dumbo 3GR Tomoko Burmese RRLM Mysti of RMIS Russian Blue Point Dumbo RRLM Mirko Burmese Dumbo RRLM Henrietta Giggles Russian Agouti Dumbo Rex Dmtn Blueberries and Cream Dumbo Russian Blue Siamese STUD Roswell Hairless CWR Benton Himalayan Hairless CWR Nunez Himalayan Hairless RRLM Lady Utsu Black Berkshire Hairless RRLM Fran Fawn Dumbo Hairless RRLM Snoopy Russian Blue Agouti Dumbo RRLM Eva Black Self Dumbo RMIS Trinity Russian blue Wheaton Burmese dumbo RMIS Chocolat Burmese LVM Truex Russian Blue Point Dumbo 3GR Tomoko Burmese RRLM Mysti of RMIS Russian Blue Point Dumbo RRLM Mirko Burmese Dumbo RRLM Henrietta Giggles Russian Agouti Dumbo Rex Produced using Breeders Assistant for Rats Pedigree Software (tel: +44 1223 290291), Personal Edition licensed to Tracie Artea.
