How to get the phenotype ratio

WebUsing monohybrid cross we can determine the phenotypic ratio of an individual. F1 Generation: Mendel cross-pollinated a pure tall pea plant (100-120cm) and a pure dwarf pea plant (22-44cm). He called them parental generation. He collected the seeds produced by this cross and grew plants from them. All of these plants were found to be tall.
