WebOct 30, 2024 · In the F2 generation of Mendel's dihybrid cross, the phenotypic ratio is 9:3:3:1 but here 9 and 1 represent the parental types i.e., they show the parental phenotype but 3 and 3 represent the recombinants i.e., showing one character of one parent and the other character of another parent. So, the phenotypic ratio of recombinants is 3:3 i.e., 1:1.

This is called a monohybrid cross: "mono" because only one trait varied, and "hybrid" because offspring represented a mixture, or hybridization, of plants, as one parent has one version of the trait while one had the other version.
WebCrosses in which F1 plants heterozygous for a given allele are crossed to generate a 3:1 phenotypic ratio in the F2 generation are known as _____. RR x rr.
