Questin- What if the bunnies I was breeding had the genotypes of WWll and wwLL. How many generations would I need to wait to get a short haired black bunny? Use Punnett Squares to show why.

So the only gametes produced from each parent are Wl and wL, respectively. 

That means all offspring will be WwLl, the punnet square looks like this|dw:1476746016472:dw|

Next, if we cross two heterozygous individuals (WwLl) that produce all possible variations of the gametes, WL, wL, Wl, and wl, we get:

|dw:1476746135763:dw|

Now all you need to know if the genotype associated with short black haired bunnies (which you didn't provide), although this cross will produce all possible genotypes, the number of new generations to achieve this phenotype is 2.
