3 dominant to 1 recessive
The ratio of Xe and F2 is 1:1
Asuming that the F1 generation is heterozygous for a single trait and that the F2 cross is of 2 F1 offspring. Ex. Aa X Aa the phenotypic ratio is 3:1 dominant to recessive. The genotypic ratio is 1:2:1 AA:Aa:aa.
the F1
Your answer is A
3:1

3 dominant to 1 recessive
All of the F1 generation are heterozygous, therefore 100% exhibit the dominant phenotype. The F2 generation has a ratio of 1 homozygous dominant: 2 heterozygous: 1 homozygous recessive. This results in a phenotypic ratio of 3 dominant: 1 recessive.
All of the F1 generation are heterozygous, therefore 100% exhibit the dominant phenotype. The F2 generation has a ratio of 1 homozygous dominant: 2 heterozygous: 1 homozygous recessive. This results in a phenotypic ratio of 3 dominant: 1 recessive.
For monohybrid cross the genotype ratio in f2 generation would be 1:2:1 and phenotype ratio would be 3: 1
9:3:3:1 was the ratio of Mendel's f2 generation for the two factor cross.
3.1
In Mendel's experiments, the ratio of tall to short plants in the F2 generation is typically 3:1. This is known as the Mendelian ratio, which is a result of the segregation of alleles during gamete formation and fertilization.
3:1
For each of the seven characters Medel studied,he found the same 3:1 ratio of plants expressing the contrasting traits in the f2 generation.
Asuming that the F1 generation is heterozygous for a single trait and that the F2 cross is of 2 F1 offspring. Ex. Aa X Aa the phenotypic ratio is 3:1 dominant to recessive. The genotypic ratio is 1:2:1 AA:Aa:aa.
