The cross of pure line of guinea with AA/bb and aa/BB genotype using a punnet square result to a F1 generation of AaBb gene combination

TO get F2 generation a male of AaBb gene combination is crossed with a female of AaBb gene combination as in figure below.

The F2 individual that are result of recombination egg being fertilized by a recombinant sperm (AaBb) are 4/16
