The recessive trait phenotype disappears in a one-trait test cross in the F1 generation. This phenotype can reappear in the F2 generation.
For monohybrid cross the genotype ratio in f2 generation would be 1:2:1 and phenotype ratio would be 3: 1
it is ratio of mono hybrid cross found in f2 generation .this ratio is 3:1
F1 and F2
Using the symbols "P" and "p" for genes, symbolize the parental cross, the F1 cross. and the F2
F2 refers to the F2 generation in genetics. First you have the P1 generation, or the 1st parents to cross. Next, their offspring is called the F1 generation. When the F1 generation offspring cross, then the F2 generation appears.
The F1 generation consists of the offspring of a cross between two parents; the F2 generation consists of the offspring of a cross between two individuals in the same F1 generation.
9:3:3:1 was the ratio of Mendel's f2 generation for the two factor cross.

F1 are the first set of offspring, and F2 are the F1's offspring.
In the P generation, one parent is homozygous dominant and the other parent is homozygous recessive. In the F1 generation, the product of a cross between the P generation, the offspring are all heterozygous. In the F2 generation, the product of a cross between the F1 generation, the expected result is 1/4 homozygous dominant, 1/2 heterozygous, and 1/4 homozygous recessive.
In the P generation, one parent is homozygous dominant and the other parent is homozygous recessive. In the F1 generation, the product of a cross between the P generation, the offspring are all heterozygous. In the F2 generation, the product of a cross between the F1 generation, the expected result is 1/4 homozygous dominant, 1/2 heterozygous, and 1/4 homozygous recessive.
A cross between members of the F1 generation (Tt x Tt), results in the genotypic ratio of 1TT:2Tt:1tt genotypes in the F2 generation. Because the tall allele is dominant, the phenotypic ratio would be 3 tall:1 short in the F2 generation.
it is ratio of mono hybrid cross found in f2 generation .this ratio is 3:1
