9:3:3:1 was the ratio of Mendel's f2 generation for the two factor cross.
The first generation of offspring from a cross is called the F1 generation.
3:1
3.1
3 dominant to 1 recessive
it is ratio of mono hybrid cross found in f2 generation .this ratio is 3:1
The Ratio is 3:1
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 ratio of dihybrid cross
incomplete dominance
