The Ratio is 3:1
The ratio of dominant traits to recessive traits in a given characteristic depends on the specific genetic makeup of the individual. In general, dominant traits are more commonly expressed than recessive traits. However, the ratio can vary depending on the specific traits being considered and the inheritance patterns involved.
The ratio of dominant to recessive traits in the F2 generation of Mendel's experiments was 3:1. This is known as the phenotypic ratio for a monohybrid cross, where three individuals display the dominant trait for every one individual displaying the recessive trait.
its 3:1
Recessive traits were visible in the F2 generation of Mendel's experiments, where the offspring of the F1 generation showed a 3:1 ratio of dominant to recessive traits.
In Mendel's experiments, the recessive traits were observed in the F2 generation. Initially, the traits were not visible in the F1 generation, where only the dominant traits were expressed. However, when the F1 plants were allowed to self-pollinate, the recessive traits reappeared in the F2 generation, typically in a ratio of about 3:1, dominant to recessive.

The traits were recessive.
In a two-factor cross where both parents are heterozygous for two traits (e.g., AaBb x AaBb), you would expect a phenotypic ratio of 9:3:3:1 in the offspring. This ratio represents the combinations of the dominant and recessive traits for both factors. The 9 represents the offspring with both dominant traits, while the 3s represent the combinations with one dominant and one recessive trait, and the 1 represents the offspring with both recessive traits.
1:3
When a first generation plant self pollinates, the ratio of dominant to recessive traits in the second generation plants is typically 3:1. This is based on Mendel's principle of segregation, which predicts that in a monohybrid cross, three plants will exhibit the dominant trait and one will exhibit the recessive trait.
Using a Punnett square, you can calculate the genotype and phenotype of two dihybrid plants. For example, if you have two heterozygous individuals for two dominant traits (we'll pretend the genotype is YyRr), put them into a Punnett square, and you'll get these results: YYRR: 1, YYRr: 2, YYrr: 1 YyRR: 2, YyRr: 4, Yyrr: 2 yyRR: 1, yyRr: 2, yyrr: 1 Phenotypes expressed: Dominant for both traits: 9/16 Dominant for trait 1: 3/16 Dominant for trait 2: 3/16 Recessive for both traits: 1/16 Therefore, the ratio would be 9:3:3:1
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.
