Question

Can you show the cross on how to get the answers? What is the ratio that is expected with independent assortment? Can you explain anything else related to it ?

Nonindependent assortment 

Experiment
Question: Do the genes for flower color and pollen shape
in sweet peas assort independently?
Methods Cross two strains homozygous for two
different traits.
P generation
Homozygous strains
Purple flowers,

Pollen
Fertilization
F, generation
