Detailed Solution

Phenotypic ratio of monohybrid crosses is when dominance and recessive relationships are applicable.

= 3 : 1
Incomplete dominance, dominance and recessive relationship are not applicable, thus its phenotypic ratio is = 1: 2 : 1

When a dihybrid cross involves one pair with dominance and recessive relationship and another pair with incomplete dominance, the resultant phenotypic ratio would be
(3 : 1) multiplied with (1: 2: 1) = 3 : 6 : 3 : 1 : 2 : 1
