Answer:
Phenotypic ratio of dihybrid cross = 9:3:3:1
Explanation:
The ration obtained in F2 generation raised from a dihybrid cross through selfing or in the ratio obtained in F2 generation raised from a dihybrid cross through selfing or inbreeding of F1 individuals. Total four phenotypes are formed in F2 generation of a dihybrid cross.
Phenotypic ratio of dihybrid cross = 9:3:3:1
Dihybrid cross is made to study the simultaneous inheritance of two pair of Mendelian factors of the genes.
Monohybrid cross is made to study the simultaneous inheritance of a single pair of Mendelian factors of the genes.
