The F Stuff
... and some basic genetic inheritance ... explained |
||
|
To see how Poodle Specific
or Labrador Specific disease causing genes can pass
down the generations, meet up and wreak havoc in Labradoodles, hold
your mouse over the picture below. |
As you can see, if the gene is breed specific, like
SA in the Poodle or prcd-PRA in the Labrador,
it cannot produce affected individuals in
the F1 generation, it can however, produce "carriers"
of the disease. |
Two F1's who are carriers for the gene can
produce F2 puppies that are affected by the disease. The illustration
below shows how an F3 puppy was "affected", because
both of his parents were carriers and he inherited one dodgy
gene from each parent. |
