In a typical Mendelian cross which is a dihybrid cross, one parent is homozygous for both dominant traits and another parent is homozygous for both recessive traits. In the $f_2$ generation, both parental combinations and recombinations appear. The phenotypic ratio of parental combinations to recombinations is ..................
