F2 generation phenotypic and genotypic ratio

WebPlants of F1 generation are allowed to interbreed freely among themselves to get F2 generation. In F2 generation, tall red, tall white, dwarf red and dwarf white will be in the ratio of 9:3:3:1. Thus F2 phenotypic ratio is 9:3:3:1. F2 tall red plants will have 4 genotypes, i.e. homozygous tall homozygous red (TTRR), homozygous tall heterozygous ... WebApr 10, 2024 · The phenotypic ratio in this is similar to the genotypic ratio i.e, 1:2:1. The first number depicts the dominant trait while the last depicts the recessive trait in the ratio. The middle number indicates the blending result of both alleles. The normal phenotypic ratio in F2 generation is 3:1 and the genotypic ratio is 1:2:1.

WebSolution. The correct option is C. 1:2:1. In the F2 generation of a typical monohybrid cross, we get homozygous and heterozygous combinations. These combinations appear in the following ratio. 1 (homozygous dominant): 2 (heterozygotes):1 (homozygous recessive). Thus the genotypic ratio of a monohybrid cross is 1:2:1. Suggest Corrections. WebThe phenotypic ratio of the F2 generation of a trihybrid cross is 27:9:9:9:3:3:3:1.
