Rabbit genetics problem for practice

#1 Fill in the punnet square for a pair of New Zealand Whites that produce offspring with buck teeth. Use N to denote the normal version of this gene and n to denote the buck tooth version of this gene. NN = Normal teeth: non-carrier, Nn = Normal teeth: carrier, nn = Buck teeth.

If both parent appear normal but are carriers then:
How many offspring will be normal (NN)?_____
How many offspring will have buck teeth (nn)?_____
How many offspring will be carriers like the parents (Nn)?_____

#2 Fill the punnet square for a cross between a black Netherland Dwarf (genotype aaBBDDEE) and a blue Netherland Dwarf (Genotype: aaBBddEE) (Hint: Both are homozygous!)

Now if the black rabbit had a blue parent (like in the above problem) was crossed black to a blue rabbit, what would happen?
