Step 1
Phenotypic ratio of a cross between two pure breeding organisms will result in all the progeny having heterozygous condition and the dominant phenotype will be expressed. For a monohybrid cross, such ratio will be 4:0.
Therefore,
Phenotypic ratio when crossing two pure breeding organisms - 4:0.
