[pyrnet] Dwarfism

["Kerry Kern Woods" <woodskk@eburg.com>]

I asked Linda Weisser (co-chair health comm.) about what has been
found out about carriers of dwarfism.
Below is Linda's answer to my query.

Any dog with *a* carrier parent has a 50% chance of being a carrier.
The
possibility *never* declines and it cannot be diluted.  IOW, if a dog
has a
known carrier 10 generations behind, statistically it has a 50% chance
of
being a carrier.  The exact same statistical possibility as if the
carrier
were the parent of that dog.  A dog that has carrier "parents" (as in
two)
may well be a dwarf.  If it is a litter mate to dwarfs, its chance of
being
a carrier statistically rises to 2/3rds.
However, any dog with a carrier in its pedigree has
a 50% chance of being a carrier.
