pls show  f1,f2 and f3 generation of dihybrid cross

F2 generation is formed after mating organisms of the F1 generation which are obtained by mating organisms which are pure breeding dominant or pure breeding recessive for a particular trait. The organisms are heterozygous in the F1 generation and when they are mated they give rise to both homozygous and heterozygous organisms for that trait in the F2 generation.
