You are given two true-breeding groups of rabbits. the first group has white hair. the second group has black hair. the second group has black hair. when you perform a cross of these two groups to obtain an f1 generation, you see that all of your rabbits have grey hair. what would you expect of the f2 generation?

Well what is expected is a mode of inheritance that is incomplete dominance as the f1 offspring organisms are all heterozygous and that would mean that they would be intermediates of the 2 pure breeding parents, and have their own phenotype.

If you cross 2 f1 generation offspring

The resulting phenotype would be 1 white rabbit : 1 black rabbit : 2 grey rabbits.
