.A 3:1 ratio of phenotypes is characteristic of a monohybrid F2 generation.

This 1:1 ratio is normally produced as a result of a test cross, if a a heterozygous individual with the dominant phenotype is crossed with an individual with the double recessive (homozygous) genotype.

A 9:3:3:1 ratio is characteristic of a dihybrid F2 generation.

A 1:1:1:1 ratio is characteristic result of a cross between an individual, heterozygous for one allele and homozygous for the other recessive allele, and another individual heterozygous for the second allele and homozygous for the other recessive allele.
