Understand How the Dwarf Gene Works!
The dwarf gene works as a simple dominant gene.
Just " ONE " dwarfing gene will produce a dwarf rabbit. Each sire and dam will pass on one of their size genes to each offspring, which will re-combine to make two per offspring.
Since the dwarf gene is dominant, just one dwarf gene will produce a dwarf rabbit. But this dwarf gene is also deadly, if paired with a second dwarf gene. Without a normal gene as a recessive back-up, a rabbit who inherits two copies of the dwarf gene always dies.
Here are the combinations of size genes that any rabbit could receive:
What do these combinations look like in real rabbits?
A) Dwarf and Dwarf:
The rabbits that get double dose of the dwarf rabbit gene results in a "peanut." Two-dwarf-gene combination is always fatal. It is thought that the double dwarfs have digestive and brain insufficiencies. If not stillborn, they usually last only 1-3 days past birth.
B) Dwarf and Normal, or Normal and Dwarf:
The rabbits that get one normal gene and one dwarf gene are known as TRUE DWARFs.
C) Normal and Normal:
The dwarf rabbit that gets two normal genes is known as a FALSE DWARFs.
Because the Dwarf rabbit is little to start with, the false dwarf is just a little bigger than normal.
These Dwarf (false dwarfs) are still very cute of course.
Breeding together with two true dwarf rabbits, it will end up with:

Breeding together with two true dwarf rabbits, it will end up with:
- 25 percent peanuts. These will all die, of course.
- 50 percent true dwarfs. These are ideal dwarf bunnies
- 25 percent false dwarfs. These are a little bigger but still stay small and cute.
