A homozygous Tall plant (T) bearing red coloured (R) flowers is crossed with a homozygous Dwarf plant ( t ) bearing white flowers ( r ):- Give the dihybrid ratio and the phenotype of the offsprings of the $F_{2}$ generation when two plants of the $F_{1}$ generation above are crossed.
Explanation
The dihybrid ratio is 9:3:3:1, which represents the possible genotypes and phenotypes of the offspring in the F2 generation. The phenotypes are: Tall red flowers (9), Tall white flowers (3), Dwarf red flowers (3), and Dwarf white flowers (1).
