I grew up with a family of horse breeders out west. In that venue it is very acceptable to breed a daughter back to her father. However, the specimins must be perfect as possible... because the inbreed to bring out the good qualities, also doubles up on any faults or recessive genes. Thus, you would need to know and understand your lines - not just the one generation or so back. With yorkies & all the health concerns regarding their health in strong, solid outcrosses; I believe this close inbreeding would not be desirable. Too high of a percentage of creating defects. It would be better to try a cousin or uncle, if you desired to try to set the trait and even that is very close. |
