The cross of heterozygous AaBb as parental phenotype led to formation of 16 phenotype of the offspring. This is because this is dihybrid form of inheritance. The probability of having aabb offspring is 1/16 since there is only one aabb type of offspring phenotype out of the 16. An illustration of how crossing is done is as per punnet square below
