Yes
No, Mini Rex Rabbits are almost twice the size of a Netherland Dwarf Rabbit.
The size and the ears are the main difference. Netherland Dwarf rabbits are 2-2 1/2 # and they have tiny upright ears. Mini Lops weigh 6 to 6 1/2 # and have lopped ears.
The common number is between 6 and 8, but they can have any number between 1 and 13.
